I am currently rating this as one star because it should not overwrite files by default! This is potentially very dangerous.

You should copy the directory, and make the changes in the copied files. If this is implemented, I will reconsider my rating. The idea is fine btw ...

[~,idx] = min(abs(X(:)-b))
c = X(idx)

would do.

@Ofer To combine strings with doubles you can use a cell array. You can use allcomb to retrieve the indices, as in

D = [10 11] % doubles
S = {'s1','s2','s3'}
ix = allcomb(1:numel(D), 1:numel(S))

This is an excellent implementation of a very efficient method. Together with the exhaustive documentation this submission is useful, usable and valuable for the productive work and education. Thanks, Jos!

A tiny simplification: You do not need B(:)', because B is a row vector already.

Does not work but is easily corrected.
Change to : zeros(NQ-2,1)],zeros(NQ-1,1)); etc
