Routh's array in symbolic way 1.0

[M L] = routh_hurwitz(P,N)This function gives the Routh's array from a numerical or SYMBOLIC polynomial and includes two special cases: (1) the first element of the row is zero; (b) a row of zeros.P Numerical or symbolic array of coeficients. In the case of symbolic variables it is necesarry to define them as: >> syms a b c ...N Digits to be considered zero a number. E.g, for N=5, 10^(-5) is considered a zero. By default, N=10M Routh's array without any simplification (e.g., with epsilon notation)L Simplified first column of Routh's array with simplification (e.g., using the limit when epsilon tends to zero) that determines the number of roots in the right-half of the s-plane: the number of changes of signs in LExamples:1. [M, L]=routh_hurwitz([1 0 2 3 4])2. syms a b c d K; [M, L]=routh_hurwitz([1 b c d+a*K])3. syms k; [M, L]=routh_hurwitz([1 k 1 1])4. [M, L]=routh_hurwitz([1 -3 -15 -9 -58 12 72])5. syms a; [M, L]=routh_hurwitz([1 0 2 3 a])
