y(1)=sin(1)
D = [1/pi*3 ,1];
N = chebop(D);
N.lbc = [1];
N.rbc = 1 - sin(1);
N.op = @(t,x,y) diff(y,2) + (2/x)*diff(y,1) + (1/(x^4))*y;
[x, y] = N\0;
plot([x, y]);

Hi,
The error you received indicates that the operator fails to evaluate the initial guess. To resolve this error, we can assign the initial guess with the boundary conditions.
N.init = [0; sin(1)];
Hope this helps!!
