I am using savefig(filename(k)); all the filenames have a datestamp at the end. ex- "F_BTW_0998_180702.mat","F_BTW_0998_180703.mat","F_BTW_0998_180704.mat" etc. but the sabove savefig command saves figure as "F.fig" , "_.fig" , "B.fig" ..etc it is oly saving as one alphabet rather the full filename

Yea, that's because (k) in your code grabs the letter with index 'k'. If you loop over the files and replace the name filename in each iteration, just remove (k) from filename(k) and you should be fine.
Please, next time include the code in your original submission. This could have been resolved in two minutes.

[~, basename, ~] = fileparts(NameOfMATFile);
filename = [basename '.fig'];
savefig(filename);

Hi Amit, are you sure that file names are stored correctly in the variable "filename"? Can you send what you have tried so far?

yes, the filename stores "F_BTW_0998_180702". and i used savefig(filename(k)); where k=1:25 (total 25 files)
but it saves the figures are 1). F.fig 2). _.fig
it only saves 1 alphabet of the filename

Hi, you should store filenames in a cell array
like
filenames = {'F_BTW_0998_180702'; 'F_BTW_0998_180703'; 'F_BTW_0998_180704'};
this will allow you to get the full name instead of letters
after this, you can do something like this:
y = randi(10,1);
for i=1:3
y1=i*y;
plot(y1)
filename = char (filenames(i)); % savefig can not take cell class variable so convert to char
savefig(filename)
end
