Interface MatDecomposition
- All Known Implementing Classes:
- LUDecomposition, SingularValueDecomposition
public interface MatDecomposition
represents a decomposition of a matrix so that it can be used to solve
linear equations. Thus to solve AX = B, where A is a Mat and B is a Vec
of the same size, and X is the unknown Vec,
use MatDecomposition decomp = new ConcreteMatDecomposition(A);
where ConcreteMatDecomposition implements MatDecomposition. For most
algorithms, the constructor will destroy the original Mat and use it
to store the decomposition. See Numerical Recipes, chapter 2
To actually solve the equation, use decomp.solve(B). See
solve(Vec).
This will replace B by the solution X (B is destroyed).
To get the inverse of the original matrix, use inverse()
this returns a new Mat that is the inverse of the original A;
