Description

The Horner block evaluates a polynomial where the argument is an input and the result of the evaluation, the output. The polynomial coefficients may be given as a vector block parameter or as a second input vector. The coefficients of the polynomial are arranged in the vector in descending order (the last vector entry thus corresponding to the constant term). The argument may be a matrix. The polynomial is evaluated for each element of the input matrix separately producing as output a matrix of identical size. Double and complex data types are supported.
