Define two functions in IML

JerryLee — Mon, 05 Dec 2011 18:56:41 GMT

I know how to define the first function, like

start f(x);

a=x[1];b=x[2];c=x[3];

f1=a complex expression involving a,b and c;

return(f1);

finish f;

What if I want to define another function g(z), where z=(x[1],x[2]) a subvector of x, such that g(z)=f(x[1],x[2],x[3]=4)? Is there a simple way to do it in IML? Thanks.

return(f1);

finish f1;

start f(x);

return( f1(x[1], x[2], x[3]) );

finish f;

start g(x);

return( f1(x[1], x[2], 4) );

finish f;
