'Not enough input arguments' error when using integral function

So i have this function

 function y = aRIC_rea(W,x)

    R=W(1); Rp=W(2); Cp=W(3); I=W(4); Ce=W(5);

    A=1+((2*pi*x).*Rp*Cp).*((2*pi*x).*Rp*Cp);

    a1= (2*pi*x).*(I.*A-Rp*Rp*Cp);
    a2= A.*(1-(2*pi*x).*(2*pi*x)*I*Ce)+(2*pi*x).*(2*pi*x)*Rp*Rp*Cp*Ce;
    a3= R.*A+Rp;
    num= a1.*a2-(2*pi*x).*a3.*a3*Ce;

    a4= (2*pi*x).*Ce.*a3;
    denom= a2.*a2+a4.*a4;

    y= num./denom;

 end

I try to integrate in a separate script

 W1 =  [0.8329    5.9045    0.0178    0.0032    0.0011]
 X1 = reshape(X,1,24)
 funRea = @(W1,X1)aRIC_rea(W1,X1)
 q = integral(funRea,5,Xres)

I get this error

 funRea = 

    @(W1,X1)aRIC_rea(W1,X1)

 Not enough input arguments.

Your code lacks the definition of X and Xres to run on my machine but I'll still give it a try.

I assume that the line

q = integral(funRea,5,Xres)

means that you want 'funRea' to be evaluated from 5 to some scalar 'Xres'.

I also deduct from your code that you want 'funRea' to be evaluated from x = 5 to Xres.

In order to achieve that you need a basic structure like

W = [1.1 2.2 3.3];

f_handle = @(x) my_function(x,W);
integral(f_handle,5,10)

function y = my_function (x1,x2)
    y = x1.^2 + x2(1);
end

Notice that 'integral' expects a function handle with only one input, here it's 'x'. The second input of 'my_function' gets fed directly during the declaration of the function handle 'f_handle = @(x) my_function(x,W)'.
