Solve using loops in MATLAB (not by paper) also please provide steps explanations and screenshots of the code and output.

1c. Reshape Previously you reshaped a column vector into a rectangular matrix using the reshape command. For example, if we start with a sample vector which is 20 elements long, then we can reshape to a 5 x 4 (or 4 x 5 or 10 x 2 or 2 x 10) using Matlab code such as: Vec = [1:20)'; M=5 ; N=4; ReVec = reshape (Vec, (M,N]) Given the same intial vector Vec, replicate ReVec using only nested loops. You code should work for any properly allowed values M and N where M*N=original length of Vec. Also, in this example create an initial vector which is quite long (e.g. 20,000 elements) and use tic and toc in your code to estimate the time used by reshape and the time used by your code. Definitely avoid printouts in this exercise. Which is faster and by how much? id. Matrix Multiplication Matrix Multiplication of an Mx P matrix (A) with a P x N matrix (B) yields an M x N matrix (C) with the Matlab command: C=A*B Replicate this result by using three nested loops. Your code should work for any compatible matrices A, B
