Hi
I am trying to load, rename and save a group of mat files . so far I am using this code :
cd 'E:\Mat'
fileFolder = fullfile('E:\','Mat');
% cd (fileFolder)
dirOutput = dir(fullfile(fileFolder,'*.mat'));
fileNames = {dirOutput.name};
for k=1:length(fileNames)
H=fileNames{k};
movefile(H, sprintf('All_state_action_qs_%03d.mat', k));
end
although it does rename all the files properly, when I load any files (with new name) the name on the work space is the old name.
Therfore, I guess there is a way for doing Load>Rename>save again in a batch fashion.
regards

@caesar: putting numbers into variable names is a sign that you are doing something wrong. It is unlikely to help you, just make your code complex, slow, obfuscated, and buggy.
"also I would be grateful if you can tell me how can extract the vector from within those mat files and stack them in one N*24 matrix"
I get the feeling that you are not actually asking us what you are really trying to achieve:
Probably it would also help if you uploaded some sample data, by clicking the paperclip button.

Ok , sorry if did confuse you . assume I have the following code
all=[];
first_1=[1 1 1 1 1 1];
first_2=[2 2 2 2 2 2];
first_3=[3 3 3 3 3 3];
save('firs_1.mat','first_1');
save('firs_2.mat','first_2');
save('firs_3.mat','first_3');
and I want to :
1- load first_1.mat,firs_2.mat and firs_3.mat
3- rename vectors first_1,first_2 and first_3 to:
first_11,first_12,first_13
3- save them in mat files :
firs_11.mat,firs_12.mat and firs_13.mat
3 - Form ALL that looks like :
all =
1 1 1 1 1 1
2 2 2 2 2 2
3 3 3 3 3 3
I hope this time its clearer
thanks

"the name on the work space is the old name" What do you expect? It's the names of the variables contained in the mat-file. They aren't affected by the name of the mat-file.
How exactly do you load the renamed mat-file?
