Args |
a_mat
|
a Symmetric Positive Definite matrix, represented as a Tensor of
shape [n, n] .
|
b_mat
|
a Tensor of shape [n, k] .
|
tol
|
(float) desired tolerance on the residual.
|
Returns |
X
|
Tensor X of shape [n, k] such that A * X = B .
|
Raises |
ValueError
|
if a_mat is not square or a_mat and b_mat have
incompatible shapes.
