Using structures instead of vectors?

Hi,
I'm using ode45 and passing the solutions into another function. Currently I am using the notation
[x,A]=ode45('odes',...)
As I need a continuous function I interpolate over x and A to get the value at any point i in the integration range.
A1_x(i)=interpl(x,A(:,1),'spline')
A2_x(i)=interpl(x,A(:,2),'spline')
I have just noticed the structure notation in the MATLAB documentation. Would the accuracy of my continuous function be greatly improved if I used the
sol=ode45(@odes,...)
notation? So now the solver is outputting 'sol' which is a structure. To recode all my functions using this would take a long time but I'm willing to do it if it will improve accuracy/speed.

That doesn't look like structure notation: that looks like function handle notation. The accuracy of function handle notation is exactly the same.
