cupyx.scipy.linalg.leslie(f, s)[source]#

Create a Leslie matrix.

Given the length n array of fecundity coefficients f and the length n-1 array of survival coefficients s, return the associated Leslie matrix.

Parameters:
  • f (cupy.ndarray) – The “fecundity” coefficients.

  • s (cupy.ndarray) – The “survival” coefficients, has to be 1-D. The length of s must be one less than the length of f, and it must be at least 1.

Returns:

The array is zero except for the first row, which is f, and the first sub-diagonal, which is s. The data-type of the array will be the data-type of f[0]+s[0].

Return type:

cupy.ndarray
