Two Variable Function Generator Program for HYDAC
This two-page EAI bulletin (No. ALHC 64020) describes the F(x,y) HYDAC program, a hybrid-computer software routine that generates arbitrary functions of one or two variables using components of the EAI Digital Operations Systems (DOS). The program represents a function of one variable as 15 straight-line segments connecting 16 evenly spaced breakpoints, and extends this to two variables by defining multiple such curves at breakpoints in the second variable, with linear interpolation applied in both dimensions. Input is loaded from punched paper tape, enabling rapid setup; unused DOS components remain available for additional logic and computing tasks.
