Question I am trying to code :
- (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:

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?
