I have an application to name the output data with concatenated variable name.
a={'PrimSpeed','SecSpeed'};
for i=1:length(a)
['FFT_' a{i}]=abs(fft(V(IS:Ns)))/Ns1;
end
The output data need to be saved in FFT_PrimSpeed.

It is simpler and more efficient to use a structure:
C = {'PrimSpeed','SecSpeed'};
S = struct();
for k = 1:numel(C)
S.(C{k}) = abs(fft(V(IS:Ns)))/Ns1;
end

Even better would be to just use basic indexing.
