How can I calculate Approximate entropy?

Hi everyone,

How can I calculate Approximate entropy in Matlab?

I would like to set the following values as the vector length (m) and the tolerance (r).

m=1

r=0.5

Thanks.

If you have the Predictive Maintenance Toolbox, you can use the approximateEntropy function. See Algorithms for details.

There are several File Exchange contributions, two being: Fast Approximate Entropy and Approximate Entropy. You can find several others with an Interweb search.
