How do you write the difference equation from Z-transform?
General constant coefficient difference equations and the z-transform. General form: P(R)y = Q(R)x. z-transform P(z−1)Y = Q(z−1)X. x is called the input and y is the output or response.
How do you find the solution of a difference equation in Matlab?
Represent the derivative by creating the symbolic function Dy = diff(y) and then define the condition using Dy(0)==0 . syms y(x) Dy = diff(y); ode = diff(y,x,2) == cos(2*x)-y; cond1 = y(0) == 1; cond2 = Dy(0) == 0; Solve ode for y . Simplify the solution using the simplify function.
Can you use Matlab to solve differential equations?
You can solve the differential equation by using MATLAB® numerical solver, such as ode45 . For more information, see Solve a Second-Order Differential Equation Numerically.
