i going projection of cube onto axis. basically, doing dot product of every vertex of cube axis , compare results find out smallest , greatest values. @ end of day, these 2 values tell me point of axis projected starts , ends. have written following function that; however, thing there lot of comparisons in , because going call function thousands of time whole code runs slow. looking optimization make code faster. function has lot of comparisons , wondering if there way can minimize amount of comparisons in it. ideas? the code written in javascript considering doing on c++ , opengl open suggestions on different programming languages. function projectcube (axis, cube) { pro = dotprodcut(axis, cube.vertex0); minpro = pro; maxpro = pro; pro = dotprodcut(axis, cube.vertex1); if (pro < minpro) { minpro = pro; } if (pro > maxpro) { maxpro = pro; } pro = dotprodcut(axis, cube.vertex2); if (pro < minpro) { minpro = pro; } if (pro > maxp...

here's piece of code i'm working on, based on example previous comment. in first line, make path? extend way macintosh hd/users/..../documents/matlab (matlab folder in path ascii files i'm analyzing stored) or start @ point? i'm not sure replace 'path', 'to', 'folder' in below example. i'm more confused because current dir showing in matlab window correct 1 files i'm working stored. in case, do fullfile line? i'm trying display contents of newly truncated files. how do that? thanks! folder = fullfile('path', 'to', 'folder'); f = dir(fullfile(folder, '*.asc')); matrices = struct(); ii = 1 : numel(f) name = fullfile(folder, f(ii).name); o = dlmread(name); matrices.(f(ii).name) = o(1:80,:); end as documentation says, fullfile allows construct filename it's parts without having worry whether use / or \ file separators , without doing things messy...
