Unrecognized function or variable 'fact2'. Error in clc_Statis (line 268) Ag(p) = A1*fact2(2*p-1)^(1/p);

I have this problem occuring while run the code for graph.

[Torsten]

I can only repeat what MATLAB says: The variable or function "fact2" used in the definition for Ag(p) cannot be found in your code.

@Mathieu NOE

fact2 is not part of the Symbolic Math Toolbox.

fact2() is not defined by any Mathworks toolbox (unless it is perhaps undocumented.)

There is a definition for fact2() at https://www.mathworks.com/matlabcentral/answers/377156-error-when-using-symsum-in-function-declaration
