How can I integrate a function that has more than 1 input?

This question might be very simple but I'm very frustrated that I cant make this work. I'm trying to integrate a function that is called like this:

d=dsACst(x,zeta,nu)

where zeta and nu are known constants and I want to integrate the function using x as the variable, like this

fun=@(x)dsACst
q=integrate(fun,0,Inf)

but I get the following error:

Not enough input arguments.

Error in dsACst (line 25)
pdf=o_tpdf(x,nu);

I can tell that when the integral is calculated the values of zeta and nu are not being read (or used) How can I fix this problem? Or maybe I'm doing something else wrong.

function ds=dsACst(x, zeta, nu)
  pdf=o_tpdf(x,nu);
  cdf=o_tcdf(zeta*x.*sqrt((nu+1)./(x.*x+nu)),(nu+1));
  ds=2*pdf.*cdf;
end

The o_tpdf and o_tcdf functions are equal to the tpdf and tcdf matlab functions I have just changed the names because of my boss requested, but the functions are not altered.

fun = @(x)dsACst(x,zeta,nu)
q = integral(fun,0,Inf)

Thank you so much! It worked!
