Method Detail

• multiplyInto

   static void multiplyInto(Array<double> out, Array<double> a, Array<double> b)

• decomposeMatrix

   static void decomposeMatrix(Array<double> transformMatrix, MatrixMathHelper.MatrixDecompositionContext ctx)

  Parameters:

  transformMatrix - 16-element array of numbers representing 4x4 transform matrix

• determinant

   static double determinant(Array<double> matrix)

• inverse

   static Array<double> inverse(Array<double> matrix)
