Witrynat = toeplitz(a,b) returns a nonsymmetric Toeplitz matrix with a as its first column and b as its first row. b is cast to the numerictype of a.If one of the arguments of toeplitz is a built-in data type, it is cast to the data type of the fi object. If the first elements of a and b differ, toeplitz issues a warning and uses the column element for the diagonal. http://ramanujan.math.trinity.edu/wtrench/research/papers/TRENCH_RP_84.PDF
