How to merge data’s of multiple dot mat files in one dot matfile (one table)

Hello every one

I have multiple dot mat files like x0.mat, x1.mat, x2.mat, x3.mat

and each file contains 1D time series data. What I need is to merge those data found in each dot mat file in one dot mat file, which contains the name of the files with corresponding data's. I have attached the dot mat files

Thanks for your help

Hi,

Here is a simple solution:

for ii=1:4
           FN= strcat(['x'  num2str(ii-1)], '.mat');
           D=load(FN); 
           X_all(ii,:)=D.x;  % OR: % x(ii,:)=D.x;
end
save('ALL.mat', 'X_all')     % OR: save('ALL.mat', 'x')

Good luck.

Thank you so much for response and for the answer.you did exactly what I need but only the file name is missing, how can i add the the name of file infront of the data in the same row?

% File Names are generated and read here:
 FN= strcat(['x'  num2str(ii-1)], '.mat');
 % You can name the variables and save every individual read data back to
 % the same file name as if I understood your question correctly. 
 

Good luck.

Off Corse I have accepted your answer Dear Eshkablove, but if it’s possible please modify the algorithm to get output that look likes table below, inside of 'X_all' .

Thank you somuch for the help

Alread X_all variable contains in this row order of all imported data x0, x1, .. x3.

Here are two table formats from which you can choose whichever works for your assignment.

% In a Column Order
X_ALL = array2table(X_all', 'variablenames', {'x0', 'x1', 'x2', 'x3'});
% In a Row Order
VAR = {'x0'; 'x1'; 'x2'; 'x3'};
X_TABLE = table(VAR, X_all);

Thank you so much this worked prefectlly!!! I got all the information in 'X-Table'
