What does the following code do?
Recall that "np.dot(a,b)" performs a matrix multiplication on a and b, whereas "a*b" performs an element-wise multiplication. Consider the two following random arrays "a" and "b": what is the shape of c?
Consider the following code: what will be c?
Consider the two following random arrays "a" and "b" below: what will be the shape of "c"?
