how do i use the fzero function or any other MATLAB function to find/verify the value of 'a', like i have done using the cubic spline method. (i am pretending that i don't know what that value is)
a=5;w=-a:a/1000:a;F=2*sin(a*w)./w; %
%
w_int=-5:0.01:5; F_int=spline(w,F,w_int);plot(w_int,F_int,'o');plot(w,F, '--', w_int,F_int,'o')c = max(F_int); [~, idx] = min(abs(w_int - 0.005));d = w_int(idx);a1 = (c*d)/(2*sin(d));
