org.ejml.dense.row.decompose.TriangularSolver_CDRM
@Generated("org.ejml.dense.row.decompose.TriangularSolver_ZDRM") public class TriangularSolver_CDRM extends Object

This contains algorithms for solving systems of equations where T is a non-singular triangular complex matrix:

T*x = b

where x and b are vectors, and T is an n by n matrix. T can either be a lower or upper triangular matrix.

These functions are designed for use inside of other algorithms. To use them directly is dangerous since no sanity checks are performed.

    • solveU

      public static void solveU(float[] U, float[] b, int n)

      This is a forward substitution solver for non-singular upper triangular matrices.
      b = U-1b

      where b is a vector, U is an n by n matrix.

      Parameters:
      U - An n by n non-singular upper triangular matrix. Not modified.
      b - A vector of length n. Modified.
      n - The size of the matrices.

    • solveL_diagReal

      public static void solveL_diagReal(float[] L, float[] b, int n)

      Solves for non-singular lower triangular matrices with real valued diagonal elements using forward substitution.
      b = L-1b

      where b is a vector, L is an n by n matrix.

      Parameters:
      L - An n by n non-singular lower triangular matrix. Not modified.
      b - A vector of length n. Modified.
      n - The size of the matrices.

    • solveConjTranL_diagReal

      public static void solveConjTranL_diagReal(float[] L, float[] b, int n)

      This is a forward substitution solver for non-singular lower triangular matrices with real valued diagonal elements.
      b = (LCT)-1b

      where b is a vector, L is an n by n matrix.

      L is a lower triangular matrix, but it comes up with a solution as if it was an upper triangular matrix that was computed by conjugate transposing L.

      Parameters:
      L - An n by n non-singular lower triangular matrix. Not modified.
      b - A vector of length n. Modified.
      n - The size of the matrices.
