public interface LinearTensorSolver<T extends TensorBase<T,?,?,?,?,?,?>>

This interface specifies methods which all linear tensor system solvers should implement. Solvers may solve in an exact sense or in a least squares sense.

Method Summary

Modifier and Type	Method	Description
T	solve(T A, T B)	Solves the linear tensor equation given by A*X=B for the tensor X.

Method Details

solve

T solve(T A,
 T B)

Solves the linear tensor equation given by A*X=B for the tensor X. All indices of X are summed over in the tensor product with the rightmost indices of A as if by A.tensorDot(X, X.getRank()).

Parameters:

A - Coefficient tensor in the linear system.

B - Tensor of constants in the linear system.

Returns:

The solution to x in the linear system A*X=B.
