How to find the inital formula from engineering test data
How to find the inital formula from engineering test data
(OP)
Recently, my job seems to work out a mathematic problem.
We did many efforts on engineer test and get a perfect graph curve by discrete data (100 points).
But my customer are interested on the inital Formula for those data. Perhaps it’s a function or calculus.....not clear.
Unfortunately, Engineers and physicists distinguish between continuous data and discrete data.
Anyone leads us first step of this cross?
Books, software, method?

I am not sure, where is the right place to ask?

If you think you know the form of the equation, you may also use other curve fitting software. As a Civil Engineer I use a program called SMADA often for this purpose.
good luck

If you start fitting equations that bear some physical sense your fit will be very likely worse because in engineering equations we allways start with some approximations like linearity of the system, orthogonality of parameters etc and do not take into account noise at measurements.
