jax.scipy.linalg.block_diag

jax.scipy.linalg.block_diag(*arrs)

Create a block diagonal matrix from provided arrays.

LAX-backend implementation of block_diag().

Original docstring below.

Given the inputs A, B and C, the output will have these arrays arranged on the diagonal:

[[A, 0, 0],
 [0, B, 0],
 [0, 0, C]]

Parameters

• A (array_like, up to 2-D) – Input arrays. A 1-D array or array_like sequence of length n is treated as a 2-D array with shape (1,n).

• B (array_like, up to 2-D) – Input arrays. A 1-D array or array_like sequence of length n is treated as a 2-D array with shape (1,n).

• C (array_like, up to 2-D) – Input arrays. A 1-D array or array_like sequence of length n is treated as a 2-D array with shape (1,n).

• .. (array_like, up to 2-D) – Input arrays. A 1-D array or array_like sequence of length n is treated as a 2-D array with shape (1,n).

Returns

D – Array with A, B, C, … on the diagonal. D has the same dtype as A.

Return type

ndarray
