How to solve a differential equations?

>> syms t y
>> a= t.*y+t.^2.*sin(t);
>> ydiff=@(t,y) a

ydiff =
    @(t,y)a

I want differential equations in place of a.

what should i do?

Answer 1

[madhan ravi]

 syms t y
 a= t.*y+t.^2.*sin(t);
 diff(a,y)

Answer 2

[Star Strider]

syms t y(t)
a = diff(y) == t.*y+t.^2.*sin(t);
av = odeToVectorField(a)
a_fcn = matlabFunction(av, 'Vars',{t,Y})

You can then use ‘a_fcn’ with the MATLAB numerical ODE solvers.
