numojo.science.signal

Signal processing module (numojo.science.signal)

Implements signal processing utilities.

It is like scipy.signal in Python.

Functions

convolve2d

convolve2d[dtype: DType, //](in1: NDArray[dtype], in2: NDArray[dtype]) -> NDArray[dtype]

Convolve two 2-dimensional arrays.

Currently, the mode is "valid".

Example: 

import numojo as nm
fn main() raises:
    var in1 = nm.routines.creation.fromstring("[[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12], [13, 14, 15, 16]]")
    var in2 = nm.routines.creation.fromstring("[[1, 0], [0, -1]]")
    print(nm.science.signal.convolve2d(in1, in2))

Parameters:

  • dtype (DType)

Args:

  • in1 (NDArray): Input array 1.
  • in2 (NDArray): Input array 2. It should be of a smaller size of in1.

Returns:

  • NDArray
