How to define K(r,alpha,beta,z) this function?

function res=K(r,alpha,bta,z)
res=r.^((1-bta)/alpha).*exp(-r.^(1/alpha)).*(r*sin(pi*(1-bta))-...
z*sin(pi*(1-bta+alpha)))/(pi*alpha*(r.^2-2*r*z*cos(pi*alpha)+z.^2));
end

I have to define this K function in other script and have to use it in main program without using "res". Please help.

I do not understand the problem.

Perhaps an anonymous function will do what you want:

K = @(r,alpha,bta,z) r.^((1-bta)/alpha).*exp(-r.^(1/alpha)).*(r*sin(pi*(1-bta))-z*sin(pi*(1-bta+alpha)))/(pi*alpha*(r.^2-2*r*z*cos(pi*alpha)+z.^2));

I have to call that function in main program twice, once as it is and once by changing the parameters i.e., r,alpha,bta,etc

Put it at the beginning your script and then call it with the appropriate parameters in the appropriate places in your script.

That should work.
