kandi X-RAY | sigtool Summary
sigtool is an opinionated tool to generate keys, sign, verify, encrypt & decrypt files using Ed25519 signature scheme. In many ways, it is like like OpenBSD's signify -- except written in Golang and definitely easier to use. It can use SSH ed25519 public and private keys. It can sign and verify very large files - it prehashes the files with SHA-512 and then signs the SHA-512 checksum. The keys and signatures are human readable YAML files. It can encrypt files for multiple recipients - each of whom is identified by their Ed25519 public key. The encryption generates ephmeral Curve25519 keys and creates pair-wise shared secret for each recipient of the encrypted file. The caller can optionally use a specific private key during the encryption process - this has the benefit of also authenticating the sender (and the receiver can verify the sender if they possess the corresponding sender's public key). The sign, verify, encrypt, decrypt operations can use OpenSSH Ed25519 keys or the keys generated by sigtool. This means, you can send encrypted files to any recipient identified by their comment in ~/.ssh/authorized_keys.

QUESTION
I applied Pandas.rolling().median(), and it has a delay or phase shift (green line).
If I use Scipy.signal.medfilt() the results are not shifted (yellow line).
Why, the results are not the same?
P.S. I've tried to look into medfilt implementation, which uses sigtools._order_filterND, which I assume is not in python.
CODE:

Hello I'm trying to include in a loop the autoregressive filter function of statmodel throughout my dataframe to generate new columns.
But I have an error when running my script, which doesn't happen if I only calculate it on a single column:

QUESTION
I want to filter a signal in Python, inspired by Matlab code. Matlab has the function filter, which is supposed to be similar to scipy.signal.lfilter (from the question: Matlab filter() with SciPy lfilter()). However, I'm still getting a ValueError: object of too small depth for desired array.
ANSWER
Answered 2019-Feb-25 at 05:51SciPy's lfilter expects the b argument to be a 1-d array (or "array-like", e.g. a list), not a scalar. For example,

I have the following peak detection that I did using hilbert transform that gets the envelop of a signal, then I detect the peaks out of it.
I would like to cut out those peaks from peak 1, to peak 2, and from peak 2, to peak 3, and from peak 3 to peak 4, and so on.

Answered 2018-Sep-05 at 03:02The problem is that c3 is a list of strings. lfilter expects a sequence of numerical values. It will not automatically convert strings to numbers, so you'll have to convert those strings to numbers in your code before calling lfilter.
