Can you help me :
Create a random matrix A of m,n size entered from the keyboard. Matrix B is n,k size with k entered from keyboard
a) Remove rows i and column j of the random matrix just created. With i = (n+m)mod n and j=(n+m) mod m
b) Add i+1 rows and j+1 columns to matrix A.
c) Delete element A[i,j]
d) Giving diagonal elements of matrix A
e) Giving the transposition matrix and the inverse matrix of matrix A
f) Calculate the A*B matrix.

What values of n,m,k would you use. I am asking because you need modifications in the matrix and there might occur a dimension error.

What kind of help do you need? Like a pointer to look up input(), eye(), inv(), transpose, etc. in the help?

By the way, c) is impossible. You can set A(i,j) to some value, like 0 or nan, but you can't delete it and leave a "hole" in the matrix.

Write a code to generate a random matrix A of size m × n with m > n and calculate its Frobenius norm, ∥ · ∥F . The entries of A must be of the form r.dddd (example 5.4316). The inputs are the positive integers m and n and the output should display the the dimensions and the calculated norm value. Deliverable(s) : The code with the desired input and output
