matlab get symbolic numerator and denominator
To obtain the symbolic numerator and denominator in MATLAB, you can use the numden
function. This function takes a symbolic expression as input and returns its numerator and denominator as separate symbolic expressions. Here's an example:
syms x
expr = (x^2 + 3*x + 2)/(x + 1); % Example symbolic expression
[num, den] = numden(expr); % Get numerator and denominator
disp(num); % Display numerator
disp(den); % Display denominator
In this example, the numden
function is used to obtain the numerator and denominator of the symbolic expression (x^2 + 3*x + 2)/(x + 1)
. The numerator num
and denominator den
are then displayed using the disp
function.
This code will output the following:
x^2 + 3*x + 2
x + 1
The numerator num
is x^2 + 3*x + 2
, and the denominator den
is x + 1
.
