function eddata = delsamps(data,samps)
%DELSAMPS Deletes samples (rows) from data matrices.
% The inputs are the original data matrix (data) and
% the row numbers of the samples to delete (samps).
% The output is the edited data matrix (eddata).
% The I/O format is: eddata = delsamps(data,samps); 
%
% This function can also be used to delete variables
% (columns) by operating on the matrix transpose, i.e.
% eddata = delsamps(data',vars)';
