matlab - numerical double integral function handle -



matlab - numerical double integral function handle -

power = 2; sigma=0.1; = 1 /(sigma*sqrt(2*pi)); c= (sigma^2)*2; syms x y f = exp(-(x.^power)./c); dfdx = diff(f,x); c1 = diff(dfdx,x); f = exp(-(y.^power)./c); dfdy = diff(f,y); c2 = diff(dfdy,y); meancurvature = (c1 + c2)./ 2; gaussiancuravture =(c1 .* c2); mean_curv = integral2(meancurvature, -inf,+inf, -inf, +inf) gauss_curv = integral2(gaussiancurvature, -inf,+inf, -inf, +inf)

i've tried in limited matlab knowledge , google searching find reply error comes up:

error using integral2

first input argument must function handle.

you need pass in anonymous functions first argument. create them using @ sign. more details, check out these links
