engGetVariable

Copy variable from MATLAB engine workspace

C Syntax

• #include "engine.h"
  mxArray *engGetVariable(Engine *ep, const char *var_name);
  

Arguments

ep
   Engine pointer.

var_name
   Name of mxArray to get from MATLAB.

Description

engGetVariable reads the named mxArray from the MATLAB engine session associated with ep and returns a pointer to a newly allocated mxArray structure, or NULL if the attempt fails. engGetVariable fails if the named variable does not exist.

Be careful in your code to free the mxArray created by this routine when you are finished with it.
