graphene:matrix-near (a b epsilon)

a -- a graphene:matrix-t instance
b -- a graphene:matrix-t instance
epsilon -- a single float for the threshold between the two matrices

True if the two matrices are near each other, false otherwise.

Compares the two given matrices and checks whether their values are within the given epsilon of each other. The epsilon argument ist coerced to a single float before being passed to the foreign C function.
