这是一段ansys官方提供的利用matlab工具箱对电机模型进行优化的程序，有几个地方没看懂
% make sure platform matchesif strcmp(computer, '$ANS_EXPECTED_PLATFORM') ~= 1
h = msgbox('32/64 platform does not match calling application, exiting')
uiwait(h)
exit
end
% add installation dir to search path so .mex file can be found
originalpath = addpath('$ANS_EXEDIR')
% connect back to opticomengine
callbackinterface = optimex('connect', '$ANS_CONNECTIONSTRING')
% make sure the optimization toolbox license can be checkout out
if license('checkout','optimization_toolbox') ~= 1
h = msgbox('Optimization Toolbox not licensed, exiting')
uiwait(h)
exit
end
% set up optimization
% variables are: $ANS_VARIABLELIST
startingpoint = $ANS_STARTINGPOINT

iterationCallbackWrapper = @(x, optimValues, state) optimex('notifyiterationcomplete', callbackinterface, x, optimValues.fval, state)
options = optimset(options, 'OutputFcn', iterationCallbackWrapper)
% halt execution so debugger can be attached
% h = msgbox('attach debugger if desired')
% uiwait(h)
% attributes that user can pass to optimization algorithm
% variables are: $ANS_VARIABLELIST
% this is the objective function which returns cost
wrapperfunc = @(x)optimex('eval', callbackinterface, x)
% this is our non linear constraint function, returns no constraints
returnempty = @(x)[];
nlcon = @(x) deal(returnempty(x), returnempty(x));
% DO NOT EDIT THIS LINE - START OPTIONS SECTION
% customers can add their own options below

% restore original path

% note: comment below line if you want MATLAB to remain
% running after optimization
exit 没看懂的地方我标注了
