a. Write a R function zerdiag.v1(m) using loop to output a square matrix
whose diagonal elements are zero and the other elements are filled in by
consecutive integers from 1 to m row-wise.
For example,
zerdiag.v1(6) = [0, 1, 2]
[3, 0, 4]
[5, 6, 0]
This function should have error checking ability. If the input m cannot form
a square matrix, then the function will return an error message: "Input
number is incorrect."
b. Write a R function zerdiag.v2(m) to produce the same output as in part
(a) without using a loop.
c. Test your functions in part (a) and (b) using m=12 and m=14 respectively.
Any help with this question would be much appreciated. Thank you!
This looks like an assignment to me.
