Extrapolate values for a variable that is dependent on three other variables?
6 views (last 30 days)
I have data downloaded for three variables:
- Temperature (85x1)
- Salinity (85x1)
- Pressure (85x1)
I use the three variables to calculate Density through a function I downloaded. I have 107 files all with the same variables but with varying lengths, so the shortest file has dimensions (85x1) while the longest has dimensions (3061x1). How can I extrapolate the values if its dependent on three different variables?

Use your vectors of representative datas to calculate corresponding representive densities. Then
F = scatteredInterpolant(Temperature, Salinity, Pressure, calculated_Density);
After that, you can
interpolated_Density = F(query_temperature, query_salinity, query_pressure)
