another user defined function question

Write an user-defined function to calculate the mean value and the maximum value of the following vector. Write another function to count how many ‘0’s the vector has x = [0, 103, 0, 105, 104, 0, 99, 100, 0, 102, 0, 107, 105] need help with this one also. it jsut userdefined functions that i don't get.

x = [0, 103, 0, 105, 104, 0, 99, 100, 0, 102, 0, 107, 105]
RESULT=noofzeros(x)  %function calling
[MEAN,MAX] = meanmax(x)  %function calling
 
function result = noofzeros(x)  %function definition
result = numel(x(x==0));
end
 
function [MEAN,MAX] = meanmax(x)  %functin definition
MEAN = mean(x);
MAX = max(x);
end

x = [0, 103, 0, 105, 104, 0, 99, 100, 0, 102, 0, 107, 105] ;
iwant = nnz(x==0)
