Gentle User,
BIFIT is a program that will read a set of data, determine a least-squares
binomial expansion curve-fit, create both FORTRAN and C source codes for the
curve-fit, as well as the necessary plot files to display the agreement with
the data.
A binomial expansion in one independent variable is just a polynomial
Y=C1+C2*X+C3*X²+...
A binomial expansion in two independent variables looks like
Y=C1+C2*X1+C3*X2+C4*X1²+C5*X1*X2+C6*X2²+...
BIFIT will handle 1 dependent variable and from 1 to 4 independent variables.
The data must be in a file which has the dependent variable in the first
column followed by the independent variables.
To run the program enter
BIFIT d:\path\datafile.ext Nc No
where Nc is the number columns of data (Nc must be 2-5), No is the order of
the expansion (No must be at least 1).
A line beginning with * in the data file will be ignored. A line beginning
with $ will terminate reading.
