Question about differential equations solving

[Settler]

Hello everyone,

when I have a differential equation of the type of:

y'+a*y=g(x)+a*q(x)

how can I solve that in MatLab?

 

[Brad1979]

Are you trying to solve this symbolically or numerically? For the former use dsolve. For the later I'd try ode45 (assuming you have initial values).

Convert your DE into Runge Kutta form or state space form. Then you can use ode45 or ode23 ect. as Brad suggested.
The form you wrote is a little odd. y'=dy/dx I assume. If that's the case you can simple integrate it by hand and use matlab to manipulate the end result.
