Splits a matrix of shape (N,m) into two matrices of (N,m/2) and (N,m/2), or the top and bottom halves of the original matrix.

Parameters:

mat (NDArray) – The original matrix of shape \((N,m)\).

Returns:

The top and bottom halves of the matrix.

Return type:

tuple[NDArray, NDArray]

finds.util.rejoin(tophalf, bottomhalf)

Rejoins the top and bottom halves of a system matrix of similar. Requires that tophalf and bottomhalf have the same shape, \((N,6)\).

Parameters:

  • tophalf (NDArray) – The top half of the matrix.

  • bottomhalf (NDArray) – The bottom half of the matrix.

Returns:

The rejoined matrix.
