load rwb gives error

I've been provided some code from a new job I've started, and I've come across an error that is stopping my progess.

There is a line in one of the files

>>load rwb

and when ran, I get the error:

Error using load

Unable to read file 'rwb'. No such file or directory.

It looks like it's a color map. Is this something that I need to download and put into my MATLAB directory?

You're looking for a file called rwb.mat. Once you find it, put it in your current working folder or in a folder that's on the MATLAB search path.

I would get this from an external source?

[Steve Eddins]

It's not a file that's provided with MATLAB. I suggest looking for it wherever you got the code you're running.

Thank you! I now have at least an understanding of what to ask for.
