Problem 540. Convert hex color specification to MATLAB RGB

Here's something that comes up all the time if you deal with web pages.

Given a hexadecimal color specification of the form #FFFFFF, convert it to a 3 element MATLAB color specification. Remember that MATLAB RGB color values are between 0 and 1.

The input is a string starting with '#'. The output should be a 1-by-3 vector.

Examples:

 Input  '#0000FF'
 Output [0 0 1]

 Input  '#33FF00'
 Output [0.2 1 0]
