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 >>

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 >>

I have been reading the MATLAB questions in Stack Overflow for a few weeks, and here was a really good question that came through. With two vectors, x and y, bin the x values as if with a… 더 읽어보기 >>

I love a good visualization of data, and often cringe when I see data in a table that would be much more effective as a graph. As with many people in Boston today, I am trying to decide what to do… 더 읽어보기 >>

MATLAB challenges get thrown around the halls of The MathWorks with fair regularity. I thought this most recent one would make a good puzzler.
