hi everyone,

I have a question.

I am analysing some data which have multiple subjects. Information about every subject is stored in the MATLAB structure (.mat file)

For Example:

U1_Acc_TimeD_FreqD_FDay.mat
U2_Acc_TimeD_FreqD_FDay.mat
U1_Acc_TimeD_FreqD_FDay.mat

and so on...

I would like to create for loop which in every iteration load new data_number.mat file.

I'd like in every iteration to load next .mat file? Particularly, I don't know how to address number part of filename using load function.

I tried this code and seems it's overwritten the data!

clear;
  for nc = 1:36
      load(['U', num2str(nc,'%2d'), '_Acc_TimeD_FreqD_FDay.mat']);
  end

Thank you

load(['U_', num2str(nc,'%02d'), 'Acc_TimeD_FreqD_FDay.mat']);

load( sprintf('U_%02dAcc_TimeD_FreqD_FDay.mat', nc) );

Notice I had suggested

for j = 1 : size(data,2)

rather than

for j = size(data,2)

the second of those does only size(data,2)
