↑

Error: Function definition not supported in this context. Create functions in code file.

>> clear;clc ;

r = [0 2.5 5 7.5 10 12.5 15 17.5 20];

v = [0.914 0.89 0.847 0.795 0.719 0.543 0.427 0.204 0];

function I = simpsons(r,v)

v = 2*pi*r.*v;

n = length(v);

i=1;

I=0;

while i<=n-2

I += (r(i+2)-r(i))/6*(v(i)+4*v(i+1)+v(i+2));

i += 3;

end

if (n-i)==1

I += r(i+1)*v(i+1)

end

if (n-i)==2

I += (r(i+2)-r(i+1))/2*(v(i+1)+v(i+2))

end

end

The error message is exhaustive already: "Function definition not supported in this context. Create functions in code file."

You can create functions inside m-files only, either at the bottom of scripts or in functions. Creating functions in the command window is not possible.
