Four x Four (double) Matrix.
This class creates a list like object, which can be modified using the list protocol method. But unlike lists, its length is fixed: it always contain 16 floating point values. Thus it does not support the any list methods that would affect its length. The values within can be changed, usually via the bracket operator.
# Supported list protocol methods: mat = FBMatrix() len(mat) print mat[13] mat[12] = 1.0
Slicing is not supported by this object.
