I have folder name 1 which contain 1B.mat file to 193B.mat file. I want to read directly this files with merging in single .mat file or using direclty call by for loop
clear
PathName = uigetdir;
file_all = dir(fullfile(PathName,'C:\User:\DELL:\Desktop:\F1folder:\1'));
matfile = file_all([file_all.isdir] == 0);
clear file_all PathName
%d=dir('*.mat'); % get the list of files
x=[]; % start w/ an empty array
for i=1:length(matfile)
x=[x;load(matfile(i).name)]; % read/concatenate into x
end
b=[];
for j=1:length(x)
b=[b; x(j, 1).variable1];
end
FileName = [matfile(i,1).name(1:end-9),'.mat'];
save(FileName,'matfile','x','b');
showing error
Index in position 2 exceeds array bounds.
Error in Untitled2 (line 15)
FileName = [matfile(i,1).name(1:end-9),'.mat'];

file_all = dir(fullfile(PathName,'C:\User:\DELL:\Desktop:\F1folder:\1'));
This is strange: User names and other folder names cannot contain colons. I guess you mean:
file_all = dir(fullfile(PathName,'C:\User\DELL\Desktop\F1folder\1'));
Clearing variables is rarely useful in Matlab. Omit this to simplify your code:
clear file_all PathName
You can replace
b=[];
for j=1:length(x)
b=[b; x(j, 1).variable1];
end
by:
b = [x.variable1];
This is nicer and faster.

"getting errore" is not clear. Please post your code and the complete error message.
What does "I want to call directly this files 193B.mat files" mean?

FileName = [matfile(i,1).name,'.mat'];
The above line is enough....
