Program running in m file, but not in exe after compiling using Matlab Compiler

Hi everyone, I have build a program that run properly in m file MATLAB. but when I compile to exe using Matlab compiler, some function didn't work. here is the error command window show on matlab execute program

    undefined function or method 'maple' for input arguments of type 'char'
    error in ==> function_a at 5

codes on function_a.m is

    function function_a(msg)
    format long

    %parameter p & q
    maple('z1:=',randint(1,1,[12 20])); %these run  in m.file, but not in exe compile
    p=maple('nextprime(z1)');
    p=str2double(p);

is there any solution for that?please need your advice, many thanks

The Symbolic Toolbox functions cannot be compiled, and that applies whether you used the older Maple based toolbox or the newer MuPAD based toolbox.

If you are not using Symbolic Toolbox, but have installed a full Maple and allowed it to add in symbolic hooks in MATLAB, then still it cannot be compiled.

randint() can be replaced by using MATLAB's randi([12 20]) or (older MATLAB)

   (12 + floor((20-12+1) * rand))

nexprime is a bit more tricky to replace, but you could use

p = primes(23);   %first prime after your maximum value
p(find(p >= z1, 1, 'first'))

Hi Mr. Walter, is there any solution for these problem? because not only those codes, but there are some function m file that using 'maple'

Need your advice again, many thanks

Mr. Walter, I have change the code that you suggest before, it just like this below, isn't right?

maple('z1:=',(12 + floor((20-12+1) * rand)));
p = primes(23);   %first prime after your maximum value
p(find(p >= z1, 1, 'first'));
p=str2double(p);

old code is

maple('z1:=',randint(1,1,[12 20]));
p=maple('nextprime(z1)');
p=str2double(p);
