System object: dsp.LowerTriangularSolver
Solve matrix equation for specified inputs
X = step(H,L,B)
X = step(H,L,B) computes the solution, X, of the matrix equation LX = B, where L is a square, lower-triangular matrix with the same number of rows as the matrix B.
Note: The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object™ issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
