I have written a function that doesn' work. When I type d=apertura(500,10,25); it says Attempted to access apertura(500,10,25); index out of bounds because size(apertura)=[1,1,1].
function [D]=apertura(T_int,phi1,phi2)
%calcolo dell'apertura sintetica A=25; %km B=50; %km n=2*pi/86164; phi1=deg2rad(phi1); phi2=deg2rad(phi2);
fun= @(t) (sqrt((n*A*cos(n*t+phi1)).^2+(n*2*A*(sin(n*t+phi1))).^2+(n*B^2*(cos(n*t+phi2)).^2)));
D=integral(fun,0,T_int);
end

Have you defined a variable named ‘apertura’ earlier in your code?
