MATLAB Online에서 열기 I'm trying to learn lsqnonlin and I just tried an example and it failed to find the right answer. Here's my example: 테마복사 X = rand(16,4); a = 1; b = 2; c = 3; d = 4; y = a * X(:,1) + b * X(:,2) + c * X(:,3) ...
This example shows how to generate C code for nonlinear least squares. Data and Model for Least Squares In this example, the vectorxdatarepresents 100 data points, and the vectorydatarepresents the associated measurements. The modeled relationship betweenxdataandydatais ydatai=a1+a2exp(−a3xdata...
MATLAB Online에서 열기 Suppose you started with a functionmyfun(x)that inputs a vectorxand outputs a vector, for example: myfun = @(x) x.^2-1; x0 = [-1.5 1.5]; x1 = fsolve(myfun,x0) x1 = -1.0000 1.0000 To incorporate your constraints, you could do this: ...
, and returns a vector of residuals (the difference between the simulation results and the measured values). You will also find many similar questions posted on MATLAB Answers, several of which are mentioned in the answer Hello
If you want to apply constraints to your least-squares optimization, using FMINCON is a fairly reasonable approach to the problem. The methods most commonly used to solve nonlinear least squares problems, such as Gauss-Newton and Levenberg-Marquardt, assume the...
