function numvect = EDB1extrnums(Str,delim)
% EDB1extrnums - Extracts the numerical values in a text-string, separated by a given delimiter.
% Periods (.) are interpreted as decimal points. 
%
% Input parameters:
%   Str         Text string, [nchars,1].
%   delim       The delimiter to look for, e.g., comma, space, slash etc.
%               Can be specified as the ASCII value or as the character:
%               '/'
%
% Output parameters:
%   numvect     A list, [1,nnums], of the numerical values that were found.
%
% Uses no special functions
