Matrix-Number Conversion

matrix2num([1,0,0]) yields 100,
assumes base 10.
matrix2num([1,0,0],2) yields 4,
using base 2.
bases 2-10 only, otherwise NaN.
matrix2num([1,0,0],2,'on')
Activates rounding safety.
Because of the floating point
rounding error numbers w/more
than 16 digits will output as
NaN with this feature on.
Default is off.

num2matrix('1234') yields [1,2,3,4]
num2matrix('1234',2) yields [1,2;3,4]
Enter # of cols if you wish to limit
The characters will wrap to next row
The number is inputed as a string,
so you can convert digits like 0010,
It will yield [0,0,1,0]
