numpy.matrix manipulations
Question:
I have a question about numpy.matrix class. How can I perform such basic manipulations with matrices as adding, deleting and replacing rows and columns?
p.s. I apologize for the lame question..
Answers:
Perfectly fine question! Try examining this code:
import scipy
X = scipy.rand(3,3)
Y = scipy.rand(3,3)
print X+Y
print scipy.delete(X, 1, 0)
print scipy.delete(X, 1, 1)
X[1,:] = [1,2,3]
print X
