Syntax
[N,D] = numden(A)
Description
[N,D] = numden(A) converts each element of A to a rational form where the numerator and denominator are relatively prime polynomials with integer coefficients. A is a symbolic or a numeric matrix. N is the symbolic matrix of numerators, and D is the symbolic matrix of denominators.
Examples
[n,d] = numden(4/5) returns n = 4 and d = 5.
[n,d] = numden(x/y + y/x) returns
The statementsn =x^2+y^2d =y*x
A = [a, 1/b] [n,d] = numden(A)return
A = [a, 1/b] n = [a, 1] d = [1, b]
