How to use sprintf in a variable name?

For example, I want to do this (but it gives an error):

row = 4
col = 2
Duration_Trial(num2str('col'))_pp(num2str('row')) = length(data_stair_rise(row, col).VideoSignals)/data_stair_rise(row, col).VideoFrameRate; % expression after the '=' is not important.

What did I do wrong?

You don’t need num2str. Just use ‘row’ and ‘col’ as they are:

Duration_Trial(col, _pp(row)) = length(data_stair_rise(row, col).VideoSignals)/data_stair_rise(row, col).VideoFrameRate;

I cannot follow what you are doing, but that change should at least get you closer to what you want.
