计算矩阵的Moore-Penrose伪逆。
本函数通过SVD计算。如果 math:`x=U*S*V^{T}` 则x的伪逆为 :math:`x^{T}=V*S^{+}*U^{T}` :math:`S^{+}` 为对S的对角线上的每个非零元素取倒数零保留在原位。

支持批量矩阵若x是批量矩阵当atol或rtol为float时则输出具有相同的批量维度。

当hermitian为True时暂时仅支持实数域默认输入x为实对称矩阵因此不会在内部检查x并且在计算中仅使用下三角部分。
当x的奇异值或特征值范数hermitian=True小于阈值 :math:`max(atol, \sigma \cdot rtol)` :math:`\sigma` 为最大奇异值或特征值)时,将其置为零,且在计算中不使用。
若rtol和atol均未指定并且x的shape(M, N)则rtol设置为 :math:`rtol=max(M, N)\varepsilon` :math:`\varepsilon` 为x.dtype的 `eps值 <https://www.mindspore.cn/docs/zh-CN/master/api_python/ops/mindspore.ops.Eps.html>`_

Computes the (Moore-Penrose) pseudo-inverse of a matrix.
This function is computed using SVD. If :math:`x=U*S*V^{T}` ,Than the pseudo-inverse of x is:
:math:`x^{T}=V*S^{+}*U^{T}` , :math:`S^{+}` is the reciprocal of each non-zero element on

Batch matrices are supported. If x is a batch matrix, the output has the same batch dimension when
