There’s a question in quiz that asks us to find product of the matrix A=([[1,-3,4],[-2,10,-7],[0,1,0],[0,0,0]]) and B=([[5,0],[-2,11],[-3,12]])
The answer comes [[-1 15]
[-9 26]
[-2 11]
[ 0 0]]
according to which none of these must be ans but the answer is something else.
Even I tried doing it in python which proves my point.
Here’s the code:
import numpy as np
x=np.array([[1,-3,4],[-2,10,-7],[0,1,0],[0,0,0]])
y=np.array([[5,0],[-2,11],[-3,12]])
print(np.dot(x,y))
Hello Aaket,
Thank you for pointing out that error.
Please tell me which quiz you are talking about though so that I can fix it.
