How can I simulate a non- linear equations using MATLAB,
I wrote them already, but I have some non linear parameters in the equations, how can i get the results if i have these parameters?
Regards
Dear Esraa,
Are your equations continuous or discrete systems?
The best way is by putting the parameters static so that the final results match the right output. Once you succeed with the simulation, change the parameters and make sure about the results. However, you have to keep attention about the chaotic range limitation for the parameters, for example in logistic map, this chaotic map exhibits a chaotic behavior if the parameter r is in ( 2.75, 4) (exhibits chaos for certain parameter values)
I Understand that you want to simulate a Non-Linear Algebraic Equation. Well, Its Simple. You just give value to the non linear parameters and then simulate the output (y for instance). Of course, you have to define the values of the domain (x for instance).
Example:
x=0:0.1.10 % x goes from 0 to 10 with step of 0.1
r=4 % Parameter of the Non linear expression
y=x^2+3*exp(r*x)+5
Esraa, A way to improve the precission is to make the step more little (example, 0.001).
If you want, you can show me the equation, so I can simulate the output. Moreover, if the garph is harmonic, it doesnt mean that the result is bad
