    • set

      public Matrix3d set(double[] values, MatrixElementOrder inputOrder)
      Sets the values of the matrix by the given double array. The order parameter defines how the values in the given array are arranged (either column or row-wise).

    • set

      public Matrix3d set(float[] values, MatrixElementOrder inputOrder)
      Sets the values of the matrix by the given float array. The order parameter defines how the values in the given array are arranged (either column or row-wise).

    • getAsDoubleArray

      public double[] getAsDoubleArray(double[] result, MatrixElementOrder outputOrder)
      Returns the values of the matrix and writes it into the the given double array. The order parameter defines how the values in the given array will be arranged (either column or row-wise).

    • getAsFloatArray

      public float[] getAsFloatArray(float[] result, MatrixElementOrder outputOrder)
      Returns the values of the matrix and writes it into the the given float array. The order parameter defines how the values in the given array will be arranged (either column or row-wise).

    • get

      public double get(int row, int col)
      Get a specific value from the matrix by row and column index

    • set
