How To Create Your Own ufunc
To create your own ufunc, you have to define a function, like you do with normal functions in Python, then you add it to your NumPy ufunc library with the frompyfunc() method.
The frompyfunc() method takes the following arguments:
- function - the name of the function.
- inputs - the number of input arguments (arrays).
- outputs - the number of output arrays.
Check if a Function is a ufunc
Check the type of a function to check if it is a ufunc or not.
A ufunc should return <class 'numpy.ufunc'>.
If it is not a ufunc, it will return another type, like this built-in NumPy function for joining two or more arrays:
If the function is not recognized at all, it will return an error:
To test if the function is a ufunc in an if statement, use the numpy.ufunc value (or np.ufunc if you use np as an alias for numpy):
