error using codegen - 2021b

having difficulty turning my trained AC agent into C or C++ code, i have generated a policy function for the agent. here is the code used and the error produced:

cfg = coder.config('mex');

cfg.TargetLang = 'C++';

cfg.DeepLearningConfig = coder.DeepLearningConfig('none');

argstr = '{ones(1,19,1)}';

codegen('-config','cfg','evaluatePolicy','-args',argstr,'-report');

Undefined function 'codegen' for input arguments of type 'char'.

Error in workflow (line 153)

codegen('-config','cfg','evaluatePolicy','-args',argstr,'-report');

i am using matlab 2021b, any help would be greatley appreciated.

Question: did you upgrade versions in the last two days? You were using an earlier MATLAB version in your Trading Toolbox question?

Answer 1

[Walter Roberson]

you need to have MATLAB Coder installed and licensed.

Note: MATLAB Coder is not available for Student licences.
