MATLAB Online에서 열기 hi all, I have an objective function that I want to minimize N=10 f=@(x) ((0.0011*(x(2:1*N)-x(1:N-1)))'*exp(-0.0078*x(4*N+1:4*N+N-1)))*3/20 is it possible to create a for loop so that the function changes for each i, like this?
Open in MATLAB Online Hi, the results were obtained by another package called "1stOpt", the code is as below, guessing of initial start values is not required: ThemeCopy Algorithm = DE1; Function y = x1*((1-exp(-(x2+x3))^xdata)/(1+((x3/x2)*exp...
Objective estimates, returned as anN-by-1vector, whereNis the number of rows ofXTable. The estimates are the mean values of the posterior distribution of the Gaussian process model of the objective function. Standard deviations of objective function, returned as anN-by-1vector, whereNis the numb...

편집:Mohammad Azadi Tabar2023년 8월 10일 Hello, I would like to add some initial data (which are from previous run of the objective function) to surrogateopt to reduce the computation time. The objective function have 4 variable. I have 100 previ...

fmincon是用于求解非线性多元函数最小值的matlab函数。由于用户应用的目标函数出现以下错误，FMINCON函数无法继续执行 gaom
是你理解错了吧，应该求x，y，z 的关系吧！不明白这个表达式干嘛f=z-beta(1)*power(x,beta(2))*power(y,beta(3));
matlab lsqcurvefit 曲线拟合时程序老出错程序如下:function f =curvefun(x,XDATA)f = x(1)*log10(1 + 1/(x(2)+XDATA.^x(3)));主程序为:XDATA = [1,2,3,4,5,6,7,8,9];YDATA = [0.726,0.151,0.055,0.028,0.018,0.009,0.005,0.003,0.003];x0 = [0.1 -1 0.1];[x,res] = lsqcu
