this is my code:
syms x;
a = -5;
b = 5;
f = 1/(1+x^2);
n=57;
h = (b-a)/(2*n);
k = linspace(a,b,2*(n+1));
s = arrayfun(f,k);
I want to aplly f to all the elements of k but it gives a error "First input must be a function handle"
Thx for your time

Hi
try this:
syms x;
a = -5;
b = 5;
f = @(x)1/(1+x^2);
n=57;
h = (b-a)/(2*n);
k = linspace(a,b,2*(n+1));
s = arrayfun(f,k);
Best regards
Stephan
