tf.raw_ops.TridiagonalMatMul

Calculate product with tridiagonal matrix.

tf.raw_ops.TridiagonalMatMul(
    superdiag, maindiag, subdiag, rhs, name=None
)

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.
