program and function definition must be in separate files and function file must have same name as function
% main file
y = 1;
z = 2;
b = myfunc(y ,z)
disp(b)
% separate file with same fun name
function a = myfunc(y ,z)
a=x+z;
or
function main
y = 1;
z = 2;
b = myfunc(y ,z)
disp(b)
function a = myfunc(y ,z)
a=x+z;

Did you run the code in command window?
Matlab functions should be in m files, and as said above, the name of the function should be callable (i.e., the name of the file name should be same as the function.
Eg:
FileName is my_function.m
content of the file:
function ret_val=my_function(input1,input2)
ret_val=input1+input2;
then from command line you can call your my_function.
>> my_function(5,3)
