function, set all elements above diagonal to zero Write a function named myFunction(m) which accepts an arbitrarily input square matrix m and return a matrix half same as m, but with all elements above diagonal zeros (including the diagonal) For example, input m=[1 2 3;4 5 6;7 8 9] should return 4 0 0 7 8 0 Hint: need to figure out dimensions of the input matrix Function Save 1 Code to call your function 1 % example call 2 myFunction([1 2 3;4 5 6; 7 8 9])
