Hi! I keep getting the error "For colon operator with char operands, first and last operands must be char". with the line "for i=1:block", where block=9.
The code I'm using is as follows:
function reach_reward2(subj_num,name,block) filename = 'C:\Users\Elizabeth\Documents\MATLAB Files\Experiment Data\' subj_num]; cd (filename) dat=['RT1_' name '.dat']; Data2=dload(dat); file = [subj_num '_' name];
for i=1:block %block num = ['1' '2' '3' '4' '5' '6' '7' '8' '9']; subj = ['RT1_' name '_' num(i) '.mov']; Data = movload(subj); combined_data = ; and so on..
I'm confused as to what I'm doing wrong?

You have to initialize block as a number such as 20 or 30 or whatever.
The error message looks like block is a string - a char vector. How do you call this function?
BTW, this is not efficient:
num = ['1' '2' '3' '4' '5' '6' '7' '8' '9'];
num = '123456789';
But the repeated definition inside the loop wastes time also. It is a good programming practize to move all repeated operations out of the loop.
Most likely sprintf('%d', i) is even better to create the number as string.
