Is there a function in MATLAB which is similar to "nearZeroVar" in R?

Is there a function in MATLAB which is similar to "nearZeroVar" in R?

I am trying to replicate some work done in a textbook which uses R examples for predictive modelling. They reduce the training set with a function 'nearZeroVar'

Please find the documentation of the function 'nearZeroVar' below:

I am looking for a function similar to this in MATLAB.

There is no direct function in MATLAB like the function "nearZeroVar" in R.

However, it is possible to implement the functionality in MATLAB according to the definition of "nearZeroVar" function in R.

Please find an example implementation of the function, "nearZeroVar.m" attached, which returns "true" if a column-vector has near zero variance according to the definition of "nearZeroVar" function in R.
