Hi guys...
I am new to this forum. I was assigned a task from my supervisor.I have a low grade mems accelerometer, whose data is Y under some temperature values X (temperature is given using a hair dryer and measured with a sensor). I do curve fitting b/w X and Y and get coefficients, a0,a1,a2. Again the same accelerometer is given different temperature and get X and Y. Curve fitting them gives me another set of coefficients b0,b1,b2. Is there any way i could combine both results and get single set of coefficients for both cases.combining both test data,makes curve fitting inefficient....

Hi,

In nonlinear fitting dialog, "settings" tab, "Data Selection" page, you can select "Concatenate Fit" for "Multi-Data Fit Mode".
This will put all xy together as one dataset and do the fit so only 1 set of parameters will be given.
