cupyx.scipy.linalg.hankel

cupyx.scipy.linalg.hankel(c, r=None)

Construct a Hankel matrix.

The Hankel matrix has constant anti-diagonals, with c as its first column and r as its last row. If r is not given, then r = zeros_like(c) is assumed.

Parameters

• c (cupy.ndarray) – First column of the matrix. Whatever the actual shape of c, it will be converted to a 1-D array.

• r (cupy.ndarray, optionnal) – Last row of the matrix. If None, r = zeros_like(c) is assumed. r[0] is ignored; the last row of the returned matrix is [c[-1], r[1:]]. Whatever the actual shape of r, it will be converted to a 1-D array.

Returns

The Hankel matrix. Dtype is the same as

(c[0] + r[0]).dtype.

Return type

cupy.ndarray
