S=S(1:f-1,f+1:length(S))
,,,, error:?? Index exceeds matrix dimensions.

Yes, that would occur if S is not two-dimensional and at least f-1 elements in the first dimension and length(S) elements in the second dimension.
Are you possibly trying to remove element #f from S? If so then
S(f) = [];
or
S = S([1:f-1, f+1:numel(S)]);

Another guess:
Did you define "length" as a variable? Then "length(S)" might fail. Test this by:
dbstop if error
% start the code until Matlab stops at the problem. Then:
which length

Defining "length" as a variable is a bad idea, because you cannot use the command length() afterwards. If "length" is 50, it has a single element only. Then "length(S)" must fail if S has any value different from 1.
