示例1: tset_potri
# 需要导入模块: import torch [as 别名]
# 或者: from torch import potri [as 别名]
def tset_potri(self):
a = torch.Tensor(((6.80, -2.11, 5.66, 5.97, 8.23),
(-6.05, -3.30, 5.36, -4.44, 1.08),
(-0.45, 2.58, -2.70, 0.27, 9.04),
(8.32, 2.71, 4.35, -7.17, 2.14),
(-9.67, -5.14, -7.26, 6.08, -6.87))).t()
# make sure 'a' is symmetric PSD
a = a * a.t()
# compute inverse directly
inv0 = torch.inverse(a)
# default case
chol = torch.potrf(a)
inv1 = torch.potri(chol)
self.assertLessEqual(inv0.dist(inv1), 1e-12)
# upper Triangular Test
chol = torch.potrf(a, 'U')
inv1 = torch.potri(chol, 'U')
self.assertLessEqual(inv0.dist(inv1), 1e-12)
# lower Triangular Test
