Hi all,
I have a n*1 cell array where each value is a combination of drive letter, folder path and file name and file extension such as:
{'C:TEMP\filename1.ext'}
{'C:TEMP\filename2.ext'}
{'C:TEMP\filename3.ext'}
...
Each row has a unique file name as shown above.
Now I would like to convert this cell array into a character array where each string is reduced to the file name only withouth path and file extension:
'filename1'
'filename2'
'filename3'
...
Does anybody know how to accomplish this?
Best regards,
Florian

R=cell(size(s)); % s is your cell array
for k=1:numel(s)
S=strsplit(s{k},{'\','.'});
R{k}=S{2};
end
Result=string(R)

Simpler:
R=regexp(s,'(?<=\\)\w+(?=[.])','match'); % s is your cell array
Result=string(R)

Hi Madhan,
the result of this operation is indeed a character array, but it is only filled with '1' in each cell.

What do you mean ? see the example below:
s=cell(3,1);
s{1}='C:TEMP\filename1.ext';
s{2}='C:\TEMP\filename2.ext';
s{3}='C:TEMP\filename3.ext';
R=regexp(s,'(?<=\\)\w+(?=[.])','match');
Result=string(R)
Gives:
Result =
3×1 string array
"filename1"
"filename2"
"filename3"
