Is there any way to convert a VI from a higher version to a lower one? Many of the examples posted on this forum ar writen in te 8.2 or 8.5 versions of LV. I only have 8.0. So what should I do to be able to open the exampls I'm talking about? Thank you

QUOTE (shoneill @ Mar 26 2008, 10:04 AM) Thank you for your answer. I don't mind being slower, but not that slow... I am using some VIs from Mathematics/Scripts and formulas/1D&2D Evaluation. Acctualy, my model subvi was porely coded. I had lots of for structers wich where not necessary. Today i have recoded the whole thing so I reduced the time from 45 seconds to 0.5 seconds/fit. (That is 10-15ms/iteration.) That's a satisfying result. I think that I can do bether if I use the "eval multivariable array" vi. Frydai I will put it to the test. If you are interested to see the thing I can send it to you.

I must fit some nonlinear data. I am using LM with a Vi reference. The model inside the reference must be dynamic, so the user can modify it at runtime. I have figured out a way of evaluating an experssion passed through the data (variant) node from the main Vi. I am passing through the data node the expression of the function in a string variable and an array of string parameters. Although the fit is very good, it is taking too long: 45-58 seconds for a 2-parameter function. Did anybody encountered this problem? (Using LV 8.0 on a Athlon XP 2500+ machine.)
