mean2 is a function from Image Processing Toolbox. Cody only supports MATLAB, not the toolboxes.

Test	Status	Code Input and Output
1	Fail	%% x = 3; y_correct = 3; assert(isequal(meanOfPrimes(x),y_correct)) Error: Undefined function 'mean2' for input arguments of type 'double'.
2	Fail	%% x = [1 2 3]; y_correct = 2.5; assert(isequal(meanOfPrimes(x),y_correct)) Error: Undefined function 'mean2' for input arguments of type 'double'.
3	Fail	%% x = [3 3; 3 3]; y_correct = 3; assert(isequal(meanOfPrimes(x),y_correct)) Error: Undefined function 'mean2' for input arguments of type 'double'.
4	Fail	%% x = [7 3 8 8]'; y_correct = 5; assert(isequal(meanOfPrimes(x),y_correct)) Error: Undefined function 'mean2' for input arguments of type 'double'.
