nonlinfit
Returns a vector of fitted points according to the equation specified.
Syntax
nonlinfit(x1, [x2, x3, …, xn,], y, c, "equation", [, flag])
Argument
- xi
- The ith input vector.
- y
- The output vector.
- c
- The initial condition vector.
- "equation"
- The equation that is to be fit. Must be in double quotes.
- flag
- Specifies whether fitted values or c values are returned.

nonlinfit(x1, x2, y, {0, 0, 0},
"c1+c2*x1+c3*x2") |
Comments
"equation" must be written in the following terms: y = f(xi, ci), where i is greater than or equal to 1,
If "equation" references cn where n is greater than the length of the initial condition vector, an error occurs.
