Complete the function that adds 3 matrices together. The matrices will be numpy type and of the same dimension of 3 × 3. There are several ways to do this, any correct answer will be accepted. In [ ]: # add the matrices a,b,c together, these will have been passed to the function # as standard numpy matrices. Rememeber if you are unsure, just print the # elements to see how to access the matrix values. # there are several ways to do this, anyway you do this is fine import numpy as np def add_matrices(a,b,c): # initiate the matrix based on the assumption that the matrix is 3x3. matrix = np.zeros([3,3]) # your code here return matrix
Create a function named mat_desc() that througouhly describes a matrix, it should: Displays the shape, size, and rank of the matrix. Displays whether the matrix is square or non-square.
