I have a class that stores some of its data in a matrix. I can't figure out how to do right adds with a matrix. Here's a toy example:
class Myclass(object): def __init__(self, x, a): self.x = x # numpy matrix self.a = a # some attribute, say, an integer def __add__(self, other): # Assume other is a numpy matrix return Myclass(self.x + other, self.a += 1) def __radd__(self, other): print other >> from myclass import Myclass >> import numpy.matlib as mp >> m = Myclass(mp.zeros((2,2)), 1) >> x = mp.asmatrix(range(4)).reshape(2,2) >> radd = x + m 0 1 2 3 The matrix.__add__ sends one element at a time. That sounds slow. Do I have to grab the corresponding element of self.x and add it to the element passed in by matrix.__add__? Or is there a better way? _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
