I just need to share this one....

So today I was browsing 9GAG, saw a post like: telnet this and enjoy, starwars fans :-)

So I tried:

How to use nice colors in Matlab Plot

One major problem I always had in Matlab plotting is that other than the "default" 6-7 colors, it's hard to use different colors.

I just found a really nice solution:

Basically, you first download a small function "rgb" from:
http://www.mathworks.com/matlabcentral/fileexchange/24497-rgb-triple-of-color-name-version-2

Then, you can call:
plot(x,y,'color',rgb('olive'));


You will be able to draw a line using a "olive" color.

The available colors are as follows:

Some useful functions for subplot in Matlab

So there are two things that the subplot function in Matlab can not do.

1. Generate an "overall" title on the top of all sub-figures.
2. Make the sub-figures as compact as possible (usually very large margins will be made).

Normally, what we can do is save each sub-figure as eps or pdf, and use LaTeX to organize them. This works well and I highly recommend this way when you are preparing publication ready figures, but there are times that you just want to generate some report quickly and nicely.

So I found this two nice functions in Matlab file exchange:
1. mtit. This one will place a title automatically for you on top of everything.
2. subaxis. This one does roughly the same thing as "subplot", but with options that enables you to remove margins.
