ich have a problem with a function i created a long time ago and now have to use again but i doesn't work as i used it the last time. The fit function uses interpolated data of rheology measurements and looks like this:
if(T>b5+p*b6){ V=(bm1+bm2*(T-(b5)))*(1-0.0894*ln(1+p/(bm3*exp(-bm4*(T-b5))))); } else{ V=(bs1+bs2*(T-b5))*(1-0.0894*ln(1+p/(bs3*exp(-bs4*(T-b5)))))+b7*exp(b8*(T-b5)-b9*p); };
I have 7 interpolated curves that represent different p (pressure) values. The problem i have now is that this fit should calculate one (!) set of bm1, bm2, bm3 etc. for different values of p. I know that i had to activate or deactivate something so that origin does not calculate different sets for each p, but i tried out everything and still can't remember what i have to change. Hopefully someone here can help. If it's important, function type is set to Y-form (German Version).
Kind Regards, Tobias

problem is solved, i found out how to share parameters. Now i have another problem i already had three years ago, please see my topic "Fit Function Origin 6 vs 8".
