Question: How to generate a sequence of points that satisfies a constraint

Hi All,

I would like to generate a sequence (say 10) of points <x_i,y_i>. (i=1, 2,..,10.)

There is a predefined constraint like f(x_i,y_i)=0.01. And I don't know the close form of f() (becasue there is a intermediate parameter in f() that was caculated numerically by optimization.).

Is there any simple function, e.g. a variant of seq(), that can do this? I am looking for something looks like:

seq(f(x,y)=0.01, x=0..1, y=0..1, 0.1)


Please Wait...
