    Modifier and Type Method Description
    static boolean isEquals​(FMatrix a, FMatrix b)
    Checks to see if each element in the two matrices are equal: aij == bij
    static boolean isIdentical​(FMatrix a, FMatrix b, float tol)
    Checks to see if each corresponding element in the two matrices are within tolerance of each other or have the some symbolic meaning.

    • isEquals

      public static boolean isEquals​(FMatrix a, FMatrix b)

      Checks to see if each element in the two matrices are equal: aij == bij

      NOTE: If any of the elements are NaN then false is returned. If two corresponding elements are both positive or negative infinity then they are equal.

      Parameters:
      a - A matrix. Not modified.
      b - A matrix. Not modified.
      Returns:
      true if identical and false otherwise.

    • isIdentical

      public static boolean isIdentical​(FMatrix a, FMatrix b, float tol)

      Checks to see if each corresponding element in the two matrices are within tolerance of each other or have the some symbolic meaning. This can handle NaN and Infinite numbers.

      If both elements are countable then the following equality test is used:
      |aij - bij| ≤ tol.
      Otherwise both numbers must both be Float.NaN, Float.POSITIVE_INFINITY, or Float.NEGATIVE_INFINITY to be identical.

      Parameters:
      a - A matrix. Not modified.
      b - A matrix. Not modified.
      tol - Tolerance for equality.
      Returns:
      true if identical and false otherwise.
