silly Matlab function to show load times of .mat files under a directory

loadtimes.m

function loadtimes ( dirname )
    if isempty ( dirname ), return, end

    cmd = sprintf ( 'find %s -iname "*.mat"', dirname );
    [ ~, files ] = system ( cmd ); 
    mfiles = regexp ( files, '\n', 'split');

    for i = 1 : length ( mfiles ) - 1
        s1 = sprintf ( '%s', mfiles{i} );
        s = regexprep ( s1, ',$', '' );
        d = dir ( s );
        fprintf ( '%s, %s, %d bytes, \t', s, bytes2h ( d.bytes ), d.bytes );
        tic; load ( s ); toc;
    end
return

function [sz] = bytes2h ( bytes ) 
    if ( bytes < 1024 )
        sz = sprintf ( '%d bytes', bytes );
    elseif ( bytes < 1024 * 1024 )
        sz = sprintf ('%0.2f KiB', bytes / 1024 );
    elseif ( bytes < 1024 * 1024 * 1024 )
        sz = sprintf ('%0.2f MB', bytes / ( 1024 * 1024 ) );
    end
return
