83 wite well commented matlab function mtaroi dyinvcheck that lecture matrices and matrlx operat

In this problem, we have x is equal to minus 3 to 6 and x and y minus 3 minus 2 minus 1, 0, 1, 2

all right so here I let these are the matrix sorry the mat lab code here so mat lab matrix lab o

we have this function y equal to a times e to the power minus b x a is equal to 2 and b equal to

Hi, in Python software import Numpy as NP, import scripti dot as ST, import MAD plot lip dot pip

From the given question, we need to make a MATLAB code to solve an arbitrary linear equation, N

Question

Write a well-commented MATLAB function named MTAROI Dyinvcheck that generates a random matrix (normally distributed), calculates its inverse (inv(A)), multiplies the two matrices back together, and calculates the residual (difference from the desired identity matrix eye(n)). The function should return the residual. Write a well-commented MATLAB script program named JWIAL that calls Dyinvcheck for n = 10, 20, 40, and 210. The program should record the results of each trial and plot the error versus n using a logarithmic plot (loglog). (See help loglog for more information on how to create a logarithmic plot). What happens when the error gets big? Please turn in a printout of the programs, the plot, and a very brief report on the results of your experiments.
