LINES_POL.DLL
Plugin for FindGraph.exe (www.uniphiz.com/findgraph.htm)
*
**************************************************************
Calculate polynomial approximation on each step of interval
How to use:
Place LINES_POL.DLL in the program FindGraph subfolder "Appr".
Start FundGraph.
Start The Wizard of approximation.
On step 2 select 'User defined function'.
If all right, on step 3 your function will appear in list.
Approximation function:
Lines on Step: y(i) =Ai0 + Ai1*x...+AiN*x^N)
Parameters:
Step =
N = pow of polynomial approximation in limits from 0 to +5
Example:
Interval x: 0 - 10
Step = 2
N=3
V(U, i) = Ai0 + Ai1*U + Ai2*U^2 + Ai3*U^3
i = 1,2,3,4,5
4x5 = 20 coefficients
