Matlab numerictype/reinterpretcast equivalent in python?

Question

In Matlab there is a command to define a new numeric type for example:

numerictype(0,16,8) 

see documentation: https://www.mathworks.com/help

Answer 1

You could use np.dtype. I used your representation of your dtype in the following snippet:

import numpy as np
dtype=[('signed', np.bool_), ('word', np.int16), ('frac', np.int16)] 
mytype = np.dtype(dtype)

and you can use it in an array like so:

np.array([True,1,1],dtype=mytype)
