The following MMatrix methods differ from their C++ counterparts.
Using the index operator is slightly different than in C++. You can use the index operator to read or write an entire row of the matrix or an individual element:
>>> m=MMatrix([[1,2,3,4], [5,6,7,8], [9,10,11,12], [13,14,15,16]]) >>> print m [1.0, 2.0, 3.0, 4.0] >>> print m[0,1] 2.0 >>> m = [1,0,0,0] >>> print m[0,1] 0.0
The row is returned as a list, so you can also write
m[0,1] when you want to read values. Note however
that this will inot work for writing values because this would
just modify the intermediate list containing the row and not the
