numslabs.m

JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the p

function[n]=numslabs(A,B)
% NUMSLABS  Counts the number of 'slabs' of one array relative to another.
%  
%   NUMSLABS(A,B) counts the number of size SIZE(B) elements of A, 
%   that is,  it returns LENGTH(A(:))./LENGTH(B(:)).  The size of A 
%   must be 'compatible' with that of B.
%  
%   See also ISCOMPAT.  
%
%   'numslabs --t' runs a test.
