tf.raw_ops.TridiagonalMatMul

Calculate product with tridiagonal matrix.

Calculates product of two matrices, where left matrix is a tridiagonal matrix.

Args
superdiag A Tensor. Must be one of the following types: float64, float32, complex64, complex128. Tensor of shape [..., 1, M], representing superdiagonals of tri-diagonal matrices to the left of multiplication. Last element is ignored.
maindiag A Tensor. Must have the same type as superdiag. Tensor of shape [..., 1, M], representing main diagonals of tri-diagonal matrices to the left of multiplication.
subdiag A Tensor. Must have the same type as superdiag. Tensor of shape [..., 1, M], representing subdiagonals of tri-diagonal matrices to the left of multiplication. First element is ignored.
rhs A Tensor. Must have the same type as superdiag. Tensor of shape [..., M, N], representing MxN matrices to the right of multiplication.
name A name for the operation (optional).
Returns
A Tensor. Has the same type as superdiag.
