NormFunction
is an option for functions such as FindFit and NDSolve which gives a function to be minimized in generating results.
Details
- NormFunction->f specifies that
should be minimized in generating results.

Basic Examples (2)
Find a "best" fit for data using different norms:
| In[1]:= |
| Out[1]= |  |
The default is to find the best least-squares fit:
| In[2]:= |
| Out[2]= |  |
| In[3]:= |
| Out[3]= |  |
| In[4]:= |
| Out[4]= |  |
Use a 2-norm for estimating local error in solving an ODE:
| In[1]:= |
| Out[1]= |  |
| In[2]:= |
| Out[2]= |  |
The error measure makes a difference in the solution quality:
| In[3]:= |
| Out[3]= |  |
