Is there a matlab function similar to numpy.spacing

Is there a matlab function similar to numpy.spacing ?

[John D'Errico]

It would be far easier to answer, if you actually told people what that code does in python. Even give an example.

[Adam Stevens]

Well its a little hard to explain. I thought a google search would be easier.

It gives the difference between a number and the next clossest number depending on the precission being used.

Here is the documentation

https://docs.scipy.org/doc/numpy/reference/generated/numpy.spacing.html

It is used in scipy's DARE solution to check for stability.

From the numpy.spacing doc:

"It can be considered as a generalization of EPS ... there should not be any representable number between x + spacing(x) and x for any finite x."

Sounds like the MATLAB function eps( ) is what you want.
