I have a Matrix in Matlab Workspace having floating point data. The order of the matrix is 10x4. I want to write 1st row in A1 cell, 2nd row in A2 cell, 3rd row in A3 cell and so on into an Excel file using Matlab. How can I do that?

Regards,

Sadiq Akbar

use num2str() to convert your 10X4 numeric matrix into 10 strings.

Then use xlswrite() to write string into Excel cells.

Here's an example

filename='myfile.xlsx';

M=rand(10,4);

str=num2str(M);

for i=1:size(str,1)

xlswrite(filename, cellstr(str(i,:)), 'Sheet1', ['A',num2str(i)]);

end

Hi Sadiq,

I don't get what is the hard part that prevent you from realizing it?

Just make a judgement of whether it is swapped or not and then process it accordingly.

There are many ways you can choose to make such judgement: for example, you can do a pearson correlation between the estimated and the desired, for all the possible mutants upon swapping, and then choose the one with the hightest correlation score.
