MATLAB: Load multiple .mat files

Question

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

Answer 1

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

or

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