I am using ActiveX to import data from an Excel file in an optimization model. There is one handle object created (Sigma variable in the code), is there anyway we can convert it to a matrix? (I got the error "Operator '*' is not supported for operands of type 'handle.handle'." for any math operations that I run).

Here is my code:

sheetname = sprintf('%d%d',k,x(k)) ;  
exlSheet1 = exlFile.Sheets.Item(sheetname);
dat_range = ['A1:Y25']; % Read to the last row
sigma(:,:,k) = exlSheet1.Range(dat_range);
Temp = sigma(:,:,k)*2;

I appreciate your help in advance.

You have to use the Value property of the Range
