Given a numpy matrix (`mixed_float_matrix`) with a variety of float values, how do you convert it into a matrix, with zeros and ones (ones in place of non-zero values in the original matrix)?

This is how:

m = (mixed_float_matrix > 0).astype(int) |

You can test it like with the following:

import numpy as np # create a "random" matrix a=np.zeros(100) p=np.random.permutation(100) a[p[:10]]=127 a[p[10:20]]=42 a.reshape(10,10) # a is now a random matrix with values 0, 42 an 127 in different places a = (a > 0).astype(int) # a is now a matrix with ones and zeros |
