       A kernel for computing the solution of a linear system of equations using a triangular coefficient matrix.

       A MPSMatrixSolveTriangular finds the solution matrix to the triangular system:

       op(A) * X = alpha * B	or    X * op(A) = alpha * B

       Where A is either upper or lower triangular and op(A) is A**T or A. B is the array of right hand sides for which the equations are to be
       solved. X is the resulting matrix of solutions.

Method Documentation
   - (void) encodeToCommandBuffer: (nonnull id< MTLCommandBuffer >) commandBuffer(MPSMatrix *__nonnull) sourceMatrix(MPSMatrix *__nonnull)
       rightHandSideMatrix(MPSMatrix *__nonnull) solutionMatrix
       Encode a MPSMatrixSolveTriangular kernel into a command Buffer.

       Parameters:
	   commandBuffer A valid MTLCommandBuffer to receive the encoded filter
	   sourceMatrix A valid MPSMatrix containing the source matrix.
	   rightHandSideMatrix A valid MPSMatrix containing the right hand side values.
	   solutionMatrix A valid MPSMatrix to contain the result.

       This function encodes the MPSMatrixSolveTriangular object to a valid command buffer.

       rightHandSideMatrix and solutionMatrix must be large enough to hold at least order * numberOfRightHandSides values starting at
       secondarySourceMatrixOrigin and resultMatrixOrigin respectively.

       sourceMatrix must be at least size order x order starting at primarySourceMatrixOrigin.

   - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device(BOOL) right(BOOL) upper(BOOL) transpose(BOOL) unit(NSUInteger)
       order(NSUInteger) numberOfRightHandSides(double) alpha
       Initialize an MPSMatrixSolveTriangular object on a device

       Parameters:
	   device The device on which the kernel will execute.
	   right A boolean value which indicates if the coefficient matrix is multiplied on the left or right side of the solution. NO indicates
	   the multiplication is on the left.
	   upper A boolean value which indicates if the source is lower or upper triangular. NO indicates that the coefficient matrix is lower
	   triangular.
	   transpose A boolean value which indicates if the source matrix should be used in transposed form. NO indicates that the coefficient
	   matrix is to be used normally.
	   unit A boolean value which indicates if the source matrix is unit triangular.
	   order The order of the source matrix and, if right == NO, the number of rows in the solution and right hand side matrices. If right ==
	   YES the number of columns in the solution and right hand side matrices.
	   numberOfRightHandSides If right == NO, the number of columns in the solution and right hand side matrices. The number of rows
	   otherwise.
	   alpha A double precision value used to scale the right hand sides.

       This function initializes a MPSMatrixSolveTriangular object. It may allocate device side memory.

       Returns:
	   A valid MPSMatrixSolveTriangular object or nil, if failure.
