Why I can't use the hhspectrum

When I perform hht transformation, software prompts undefined function or variable 'hhspectrum', how should I solve it, thank you!

[Dyuman Joshi]

You get the error because there is no function named 'hhspectrum'.

Did you mean to use "hht"?

[zl]

yes！ I want to do the hht transform to get Hilbert spectrum and marginal spectrum,

I use hhspectrum function, but I get the error, I don't know how to solve it?

thank you！

" I use hhspectrum function"

There is no such function as hhspectrum.

Use the function hht (As I mentioned above as well)

Hi,

I would suggest you refer to the following link for the Hilbert-Huang transform:-

Hilbert-Huang transform

For any error or query, I suggest you post the exact error.

I hope this helps!
