Today I'll show you one way to visualize the sRGB color gamut in L*a*b* space with assistance with a couple of new functions introduced last fall in the R2014b release. (I originally planned to post... 更多内容 >>

I hesitated for some time today about where to go next in my discussion about the new default colormap in MATLAB. I finally decided to spend a little time on the reactions so far. Those reactions... 更多内容 >>

Last week I showed you the new MATLAB colormap, parula. Parula has replaced jet as the default colormap in R2014b, which was released earlier this month.This week I want to explain some of the... 更多内容 >>

I believe it was almost four years ago that we started kicking around the idea of changing the default colormap in MATLAB. Now, with the major update of the MATLAB graphics system in R2014b, the... 更多内容 >>

I'm terrible at rote memorization.I thought about that recently when I happened to see a plot (I think it was in a documentation example) that compared $sin(\theta)$, $cos(\theta)$, and... 更多内容 >>
