Exemplo da utilização de Maps em matlab
% Using Maps to have constant time complexity to access data
% See more at http://www.mathworks.com/help/matlab/map-containers.html
% Example here http://stackoverflow.com/questions/3591942/hash-tables-in-matlab
% Let's supose we have the following information:
table =[ [1 , 1 , 1 , 0.444 , 0.67 , 0.98];
[1 , 1 , 2 , 0.254 , 0.67 , 0.98]
];
% So to store them in an efficient way
