For help with GB.M and gloptipoly.m

[Umbrella9919]

HI,I run the code in my matlab(2021b), and I have installed the necessary toolbox. When I run gloptipoly.M，I got the error :

Unrecognized function or variable 'mpol'.
Error in gloptipoly (line 36)
mpol('c', 7);

I can't find the mpol function in the downloaded code, is this function in some toolbox?
When I run GB.M，I got the error :

GB
'touch' is not an internal or external command, nor is it a runnable program 
or batch file. 
'maple' is not an internal or external command, nor is it a runnable program 
or batch file. 
Wrong use of GB (line 39)
'maple' is not an internal or external command, nor is it a runnable program
or batch file.

I think I may need to set up the software, but maybe I didn't find it and would like some help

Hi,
the mpol function is part of the Gloptipoly toolbox. Are you sure you have installed it correctly?
