MATLAB: Plotting Airy equation using matlab

Question

How can I plot the airy function?

code used

syms y(t)
dsolve(diff(y, 2) - t*y == 0)
ezplot(dsolve , [-2,2])

This is the error observed

ans =

C1*airy(0, t) + C2*airy(2, t)

Warning: Empty equation.

> In dsolve (line 205)

In B4 (line 5)

Unable to perform assignment because the left and right sides have a different number of elements.

Error in ezplotfeval/applyfun (line 76)

z(i) = feval(f,x(i));

Error in ezplotfeval (line 63)

z = applyfun(x);

Error in ezplot>ezplot1 (line 486)

[y, f, loopflag] = ezplotfeval(f, x);

Error in ezplot (line 158)

[hp, cax] = ezplot1(cax, f{1}, vars, labels, args{:});

Error in sym/ezplot (line 78)

h = ezplot(fhandle(f),varargin{:});%#ok<EZPLT>

Error in B4 (line 5)

ezplot(dsolve , [-2,2])

Answer 1

Here is one of the possible solution codes:

syms y(t)
Dy=diff(y,1);
D2y=diff(y, 2);
A=dsolve(D2y - t*y == 0, y(0)==1, Dy(0)==2);
ezplot(A, [-2, 2]); % or % fplot(A, [-2,2])

Note that to plot Airy function you'd need to specify the initial conditions.
