    • hasUncountable

      public static boolean hasUncountable​(org.ejml.data.FMatrixSparseCSC A)

    • isZeros

      public static boolean isZeros​(org.ejml.data.FMatrixSparseCSC A, float tol)

    • isIdentity

    • isLowerTriangle

      public static boolean isLowerTriangle​(org.ejml.data.FMatrixSparseCSC A, int hessenberg, float tol)

      Checks to see if a matrix is lower triangular or Hessenberg. A Hessenberg matrix of degree N has the following property:

      aij ≤ 0 for all i < j+N

      A triangular matrix is a Hessenberg matrix of degree 0. Only the upper most diagonal elements are explicitly checked to see if they are non-zero

      Parameters:
      A - Matrix being tested. Not modified.
      hessenberg - The degree of being hessenberg.
      tol - How not zero diagonal elements must be.
      Returns:
      If it is an upper triangular/hessenberg matrix or not.

    • isTranspose

      public static boolean isTranspose​(org.ejml.data.FMatrixSparseCSC A, org.ejml.data.FMatrixSparseCSC B, float tol)

    • isVector

      public static boolean isVector​(org.ejml.data.FMatrixSparseCSC a)
      Returns true if the input is a vector
      Parameters:
      a - A matrix or vector
      Returns:
      true if it's a vector. Column or row.

    • isSymmetric

      public static boolean isSymmetric​(org.ejml.data.FMatrixSparseCSC A, float tol)
      Checks to see if the matrix is symmetric to within tolerance.
      Parameters:
      A - Matrix being tested. Not modified.
      tol - Tolerance that defines how similar two values must be to be considered identical
      Returns:
      true if symmetric or false if not

    • isPositiveDefinite

      public static boolean isPositiveDefinite​(org.ejml.data.FMatrixSparseCSC A)

      Checks to see if the matrix is positive definite.

      xT A x > 0
      for all x where x is a non-zero vector and A is a symmetric matrix.

      Parameters:
      A - square symmetric matrix. Not modified.
      Returns:
      True if it is positive definite and false if it is not.

    • isOrthogonal

      public static boolean isOrthogonal​(org.ejml.data.FMatrixSparseCSC Q, float tol)

      Checks to see if a matrix is orthogonal or isometric.

      Parameters:
      Q - The matrix being tested. Not modified.
      tol - Tolerance.
      Returns:
      True if it passes the test.
