Dear Friends and Team, For one of my application, I am required to use libsvm based svm regression prediction model svmpredict in simulink. Currently I tried to achieve it through Simulink library MATLAB Function block, as shown in following code block

    function y = fcn(SOC,Curr,Tamb,switch_in)
    coder.extrinsic('svmpredict','net','polyvaln','evalin','assignin','mapminmax')
    ....
    switch switch_in
    case 1
        %'model' is the output structure of svmtrain and svmpredict is
        %external function
         assignin('base','xtestn',xtestn);
         estimate_out = svmpredict(y,xtestn, model); 
         disp(estimate_out);
        estimate_out = 0;
But using this the block goes to somekind of infinite simulation, without keeping track of the time necessary to complete simulation on time.
