Debugging session 3

clear num = [1 1 1 1 1 1 1]; den = [1 2 3 0 5 6 7]; for i = 1: numel(den) if den(i) == 0 a = 1 else … 더 읽어보기 >>

Exploring uitable properties 12

I got a question via e-mail that was asking how to set the data in a uitable. Setting the data in a uitable is as easy as: >> a = uitable >> set(a,’data’,… 더 읽어보기 >>

Breaking up compound statements for the profiler 4

A statement like this: a = sin(x) + cos(y) + inv(z); makes it impossible to know which part of the calculation is the bottleneck. This video shows how to determine what is slowing your code… 더 읽어보기 >>

Flow chart shows which visualization to use 5

Nathan over at FlowingData.com had a post that explains what visualization to use in different situations. Ultimately he linked to this chart from Andrew Abela of The Extreme Presentation(tm)… 더 읽어보기 >>
