subdir: a recursive file search

Performs a recursive file search using same input and output format as dir function

This function performs a recursive file search. Its advantage over other FEX programs offering the same thing is that it uses the same input and output format as Matlab's dir function, and can therefore be used interchangeably.
Example:

>> a = subdir(fullfile(matlabroot, 'toolbox', 'matlab', '*.mat'))

a =

66x1 struct array with fields:
name
date
bytes
isdir
datenum

>> a(1)

ans =

name: '/Applications/MATLAB74/toolbox/matlab/audiovideo/chirp.mat'
date: '14-Mar-2004 10:31:48'
bytes: 25276
isdir: 0
datenum: 7.3202e+05
