How to write a conditional statement for tridiagonal matrix.

Hi! I have tridiagonal matrix function where I need to have a conditional statement if a, b, and c contain any nonzero values. If they contain a 0 then I must write an error the the program as the diagonals have to be nonzero values. Attached are the main program with comments and the function program

a = [3 4 0 8];

validateattributes(a,"numeric", "nonzero")

Expected input to be nonzero.

Thank you! How would I be able to incorporate validateattributes as a conditional statement?

You don't need to. As you can see from the output above, it does the whole task of checking whether a has the right properties from start to finish, including generating the error message.
