I have a spreadsheet with M-1 rows and N colomns. I want to calcolate the covariance matrix of the spreadsheet and i would like like output an other spreadsheet. I tried to do my self, but no so much result. here my code, but there is a mistake
View 14 RepliesI have a sheet that has consecutive dates in column A, from newest to oldest. I column B I have some stock returns. In column C I have some other stock returns. In D1, I want the covariance of the 2 stocks over the past x days (i.e. covar(B1:Bx,C1:Cx)). In D2, I want the covariance over x days as well, but only up to the date in A2 (so, covar(B2:B(x+1),C2:C(x+1))).

View 9 Replies View RelatedUsing VBA, I wish to work out the inverse matrix of a large matrix (100*100), but keep getting the # Num! Error. I am using the minverse function. I have defined variable as "variant", does this give me the same possiblities in terms of number size as the variable "Double"?
For a table like the one below produced for the sake of example (actual is much much bigger) I want to make it list rows that are true for a certain column for a certain variable in the matrix. So for say water terrain, which types of activity can I do i.e. swimming. Or for Offroad the activites which I can't do i.e. Run and Swim.
ActivityWaterRoadOffroad
Jog nym
Run nyn
Walk nyy
Swim ynn
y=yes
n=no
m=maybe
Below there are all the information needed to understand my problem.
M(1 to R,1 to C): matrix with R rows and C columns [element known]
M(i,j): elements of the matrix M in position i(row)-j(column) [element known]n
I need to get the fee value, if I write "Name" and "Time".
Please read the simple example file named "Fee from matrix".
Given one array variable (matrix n x n) M, I want to use the function sum, to sum along the rows.
I can use Application.WorksheeFunction.Sum(M)
but this will sum all the elements
and I would like smtg like this
Application.WorksheeFunction.Sum(M(1,)
Just sum the first line, or the i-th line.
I have code to create a correlation matrix (NxN, where N is the number of columns). This is done by selecting an area that is NxN, entering the function and range, then hitting ctrl +shift + enter (array formula).
However, I want to convert this to accept VBA arrays, rather than a data range, and give the output in form of an array as well.
VB:
Function CorrmatK(dataRange As Object) As Variant
On Error Goto 20
Dim r As Integer, n As Integer, rr As Integer, i As Integer, j As Integer, k As Integer, doit As Integer
Dim x() As Variant, mc() As Double, ss() As Double, m() As Double, ob As Object
r = dataRange.Rows.Count
n = dataRange.Columns.Count

I NEED some code to convert a matrix to a singel column and it should be reversed to!
see attachment!

TO:
D1
C1
B1
A1
D2
C2

I have to create a matrix from columns in this format:
A1 A2 1
A1 A3 4
A1 A4 6
A1 A8 4
A2 A5 2
A2 A8 3
with a lot of empty cells (here, for exemple A1,A6 & A1,A7 ) and (A1,A2) = (A2,A1)
I'd like to have :
_ A1 A2 A3 A4 A5 A6 A7 A8 .....
A1 0 1 4 6 0 0 0 4
A2 1 0 0 0 2 0 0 3
etc
The source data is in the attachment. Would it be possible to do it automatically?
I have this code to take an area of data and perform the SUMXMY2 formula and output the results to another sheet. My problem is that the results are being outputted in a semi-matrix and i needed them in a column so i can them perform a sort. Is this possible and can anyone shed a light on the best way to do it?

I have a matrix A with 12 rows and 10 columns. My problem is if in the cell(i,j) there is data then the same data should appear in a similar matrix B, but in a cell which is 15 cells behind the cell(i,j).
That is it should start counting upwards from cell (i,j) in B and once it reaches the top of the matrix it should continue counting from the bottom of the immediate left column and go up. When it reaches the 15 cell from cell(i,j) in b, it should print there the value that was in cell(i,j) of A.
I am trying to figure out a better way to do my mileage for when I drive for work.
Currently I need to look at a sheet and see where I started and where I stopped and then I’ll see the distance.
Kinda look something like this.

What I would like to do is type in the “to” and “from” cell and have it automatically know the miles based on the chart above.

I wasn't able to attach the file because it was too big, but you can download it from here www.easygcc.com/correl.rar. On the sheet called " Correlation" there is matrix, I am baiscally trying to fill in the correlation formula into every cell so the matrix is filled out. The data for the correlation calculation comes from the sheet called "Tech Data". I have filled in the correlation formula into a few of the cells as an example, but I don't want to continue doing this manually but rather have a macro do it for me. Otherwise this will take for ever. My macro is also a part of the file, if you would liek to look at it and maybe fix what I already have.
View 4 Replies View RelatedI have a 5 x 5 matrix. When values are entered in 2 cell there needs to be a matrix lookup and the corresponding value needs to be entered into the 3 cell. Example :
- A B C D E
V 1 2 2 3 3
W 2 2 3 3 3
X 2 3 3 4 3
Y 3 3 4 4 5
Z 3 3 4 5 5
So if X and D are entered into the 2 cells the 3rd cell should show 4.

On my example sheet it shows how many cables and how the cable length per job. What i need is for the hour/job column to be populated from the Hours sheet by matching the column and row. e.g 4 cables at 40 metres would give me cell D7 (27.89), as 25 metres would be no good - so rounding up would be required.

View 9 Replies View RelatedI'm struggling to find the right Excel functions to fill up a block matrix. Here are all the details of my problem.
I have a list of firms and relative products. Each firm can produce either 1, or 2 or 3 different products, for instance
firm A produces product x
firm B produces products y and z
firm C produces product j
firm D produces products k, h and q
Suppose the data appear on a sheet in column order, that is, one column for the firms and one for the products with a space between A, B, C and D when one firm is a multi-product producer. I need to create a 0-1 block matrix in Excel setting 1 when the product is produced by the same firm and 0 otherwise, i.e. for the above example

I have an array of data with column headings and changeable row "item names"
in the left most column. The intersecting matrix of data contains quantity
values at the intersection cells of column and row headings. I need to
automatically reorganize the data as a list in a column with the row "Item
Names" at the left but and repeated as necessary but instead of the
additional columns of quantity values, I need to have this data listed in a
single vertical column along with an additional column with the original
column header that corresponds to the quantity value. I think there must be
some kind of lookup function to do this but I can't find the right way to do
it.
I have 2 lines with pairs and 3rd with corresponding values, nee to construct a matrix out of it with formulas
Example
Need to turn

So the one that stands above in the initial file goes to the top line in the matrix. 2 line -> column in matrix. In case there is no match need to seek reverse in 1,2 and reflect as 1-VALUE in the matrix

I'm having trouble with a formula. Column A is a list of names. Row 1 is a list classes. What I need to be able to do is select a class from Row 1 in drop-down list in C14 and have it return the list of names in list starting at C17 based on the 'X'. In this example for SCIENCE it should return Tim Mark Jen. The actual file has 50+ names and 50+ classes.
