Origin Version (Select Help-->About Origin): 6.0
Operating System:windows
hello!!
I have a 1024*1024 matrix and I want to divide it by the values in the column (i,1024). I have tried Matrix1=Matrix1/cell(i,1024) and it does not work.
Thank you very much
Rebeca

The cell() function was introduced in Origin 6.0 but not documented until Origin 6.1. Its syntax also changed from one version to the next...
cell(i,j) = value at col i, row j; // Origin 6.0
cell(i,j) = value at row i, col j; // Origin 6.1 and later
In your version Matrix1=Matrix1/cell(i,1024) divides the entire matrix by the value in col i, row 1024. If you want to divide the matrix by the value in row i, col 1024 just interchange the cell() arguments.

Hi Rebeca,
I still have the latest version of Origin 6.0 on my PC and it works in that version. I recommend that you apply the Origin 6.0 Service Release 4 Patch. If you can't do that then you can duplicate the cell() function as shown below. (The string variable %H always holds the name of the active window.)
rr = enter row number;
cc = enter column number;
win -a Matrix1; // activate Matrix1
matrix -pg Dim ncols nrows; // get number of columns and rows
if(rr<=nrows && cc<=ncols) {
cellValue = %H[cc + (rr-1)*ncols]; // get value at row rr, col cc
(%H) /= cellValue; // divide matrix by cellValue
};
