Need help debugging code

Question I am trying to code :

1. (20 pts)Write a function named matAvg that will receive a matrix matas given below as an input argument and will calculate and return the overall average of all numbers in the matrix. Use for loops (not built-in functions) to calculate the average. Given

mat = [6 9 7 3; 7 3 0 1; 4 8 1 1; 6 2 2 5]

You should be able to invoke the function from command prompt as

>>avg = matAvg(mat)

SAMPLE OUTPUT

mat =

6 9 7 3

7 3 0 1

4 8 1 1

6 2 2 5

avg =

4.0625

My code:

How the code is supposed to turn out:

Your input matrix is missing in the call.

Answer 2

Look at how you call your function in your Command Window and look how the example calls it in the sample output. You're not calling it the same way the example does.

How should MATLAB know which matrix it should operate on with your function call? Did you tell it?
