MATLAB: F1(x)g1(y)dx+f2(x)g2(y)dy=0 Separation of variables

emergency solution of differential equations

Can you help me find the solution of this differential equation the MATLAB software that performs?

Use ode45 to solve

dy/dx = -f1(x)*g1(y)/(f2(x)*g2(y))

If you solved your equation by solving the System

y1'=y2
y2'=f(y)/A,

you can get y' and y'' by

yp=deval(sol.yp,sol.x);
plot(sol.x,yp(1,:),sol.x,yp(2,:));

Here, yp(1,:)=y' and yp(2,:)=y''.

Best wishes

Torsten.

f0 = deval(sol,0);
f0(3)
