System Identification - SISO -SIPO

Hello, I am UG Student I require to complete a part of my work with matlab My guide said me to go with system identification in matlab for function generation

Here is what i need: i will input a series of values and its corresponding output values!

time temp deform
0      5    18
1      4    45
2      7.8   85
3      8     72
4      5     45
5      8    41
6      4     51

The system should automatically generate a function based on the input and output values(non linear) which i have entered!

Such that i could used that function inorder to predict/compute the output values based on input values!

for example if input values say 8 it should give some predicted value(say 41)

Some one please tell me where i need to start and how to proceed this!!

Thanks a lot!

You might need to do some homework on concepts of data fitting, static (e.g. polynomial function) vs. dynamic (e.g., transfer function) modeling. You must decide the type of function ("model") you want to fit before creating/picking a scheme for estimating the corresponding coefficients.

You may want to look at the product documentations and examples for Curve Fitting Toolbox, Statistics Toolbox and System Identification Toolbox.
