def c1(a1,b1):
a1=2
b1=3
cc=a1+b1
return cc
I have saved this function in test.py. When I use this function in MATLAB I encountered this problem:
import py.test.* c1(2,3)
Undefined function 'c1' for input arguments
of type 'double'.
py.test.c1(2,3)
Undefined variable "py" or class
"py.test.c1".
How can I use .py function in MATLAB R2014b？
If you get the error message below, a failure has occurred.
Undefined variable "py" or class
There are a lot of things that might be wrong here, and Mathworks have actually set up a whole tutorial for how to troubleshoot this problem. (The title of the page is actually: Undefined variable "py" or function "py.command", so it should contain most of what you need)
Check out the following:
Starting from Matlab 2014b Python functions can be called directly - using prefix py, then module name, and finally function name like so:
result = py.module_name.function_name(parameter1);
However, one has to make sure to add the script to the Python search path when calling from Matlab (especially if the first time Python is called the current working directory is different than that of the Python script.
