Des sujet en parle déjà : http://www.mathworks.com/matlabcentral/answers/20400-encryption-of-password
Sinon, j'ai aussi trouver ce script qui permet de faire ça :
function passwordDemo
f = figure;
pwd = javax.swing.JPasswordField;
[hComp,hContainer]= javacomponent(pwd,[100,100,200,20],f);
set(hComp,'ActionPerformedCallback',@passwordEntered);
function passwordEntered(varargin)
disp(['The password entered was ', char(hComp.getText)])
end %passwordEntered
end %passwordDemo
Si cela peut aider.
