I am looking for a way to calculate curvature of this wave (pic attached) in matlab.

Sinc Wave

I have generated this wave form in Matlab.

 t2 = linspace(6,2);
y2 = sinc(t2);
subplot(212),plot(t2,y2);
xlabel('Time (sec)');
ylabel('Amplitude');
title('Sinc Function: 04');

Would be grateful if some one can help me out.

If you want to calculate the curvature of a line that is defined by a graph $\{(x,f(x)\}$ of a function $f:D\subset \mathbb R \to \mathbb R$ you can easily do that by following formula:

$$k(x) = \frac{f''(x)}{(1+(f'(x))^2)^{3/2}}$$
