How can I plot the solution of this ODE x^2.y’-y-y^2=0. Help me out please, I am new at Matlab.

You need to solve it first.
The ODE can be easily made explicit
Then you can use any Matlab ODE solver (see this documentation) to numerically solve it and then plot it using the plot function.
I suggest you give it a go, and if you stumble into problems of any sort maybe come back here and we can fix them.

Thanks for the advice, I’ll do that.

Solve the last equation for y and incorporate the boundary condition to get the constant C.
What's the problem ?
