I tried following the directions from:
on pg 8-12, but for some reason i'm getting an error with my syntax. I think it doesnt like how i'm writing apostrophe when i write y'(x).
Someone give me some ideas on how to make it work?
Thank you!

Try using dsolve from the matlab command window. y'(x) would be 'Dy' as in
dsolve('Dy = x',<initial conditions>,'x')
Edit
so for the example it should be:
syms x y;
dsolve('Dy-y^2','x')

2 things:
- Be very careful to enter y(x) (never just plain y).
- In the MuPad statement you included with your comment, you need a colon:
diffequation = ode(y'(x)-y(x)^2,y(x))
Should be:
diffequation := ode(y'(x)-y(x)^2,y(x))
instead
You can then
solve( diffequation )
