lookup n-dim table in simulink

Hi, all.

I have a function that for 4-d vector returns value. I can't understand exactly, how can I define table such that simulink automatically calls this function and fills table. For example, I have function get_val(a, b, c, d) and I need to create table with the following ranges a = -1:0.1:1; b = -2:0.2:1; c = 2:0.2:4; d = 1:0.1:5;

I found parameter 'get table and breakpoint data from' but i have no ideas how this works. What should return my function?
