Dot indexing is not supported for variables of this type.

if model.code(1) == 'c', % changed
Note
"I just used iris data"
the code :
load iris.dat
setosa = iris((iris(:,5)==1),:); % data for setosa
versicolor = iris((iris(:,5)==2),:); % data for versicolor
virginica = iris((iris(:,5)==3),:); % data for virginica
obsv_n = size(iris, 1);
X= iris(:,1:4);
Y=iris(:, 5);
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
type = 'classification';
L_fold = 10; % L-fold crossvalidation
[gam,sig2] = tunelssvm({X,Y,type,[],[],'RBF_kernel'},'gridsearch', 'crossvalidatelssvm',{L_fold,'misclass'});
[alpha,b] = trainlssvm({X,Y,type,gam,sig2,'RBF_kernel'});
plotlssvm({X,Y,type,gam,sig2,'RBF_kernel'},{alpha,b});

There is no error in what you have shared. We need to see the code where the error occurs (line 145), as well as the code used to create your variable model.
