xdata =[ 1 2 3 4 5 6] ; ydata=(1./(xdata.^2+2*xdata+4)); FitnessFunction = @(x) sum((x(1)./(x(2).*xdata.^1.9+x(3).*xdata.^0.9+1)-ydata).^2); numberOfVariables = 3; x =ga(FitnessFunction,numberOfVariables)

在 MATLAB Online 中打开

your call of ga is equivalent to

x =ga(@(x) sum((x(1)./(x(2).*xdata.^1.9+x(3).*xdata.^0.9+1)-ydata).^2),numberOfVariables)

does it make sense to you to choose a different names for the input variable in the function parameter for the ga optimization toolbox, and the output of ga?
