I have a table with mixed numeric&string content:
M =
rep file condition corrAns
___ __________________ _________ _______
1 'stimuli/03C1.wav' 'C1' 2
1 'stimuli/03C4.wav' 'C4' 1
I'd like to convert M to an array, so as to be able to save it as a spreadsheet using xlswrite, which requires an array as input.
However, the command
gives the error
Cannot concatenate the table variables 'rep' and 'file', because their types are double and cell.
I tried converting the first and final columns from double to cell using
M(:,1) = table2cell(M(:,1))
or even
for i_row=1:row_N
M(i_row,1) = num2cell(M(i_row,1));
M(i_row,4) = num2cell(M(i_row,4));
but both of these conversions lead to the same error. Any suggestions?

I recommend using writetable instead of using xlswrite. You can tell writetable to write to a spreadsheet file.

What Steve said. writetable is a much better choice.
It also looks like Condition could usefully be converted to categorical, depending on what you're doing with it.
