how to implement lookup table in matlab code

[Cedric]

What type of "key" do you need?

Mustafa Sabah's "Answer" moved here:

Any type ,please

[Cedric]

But you does "any" mean? Will you have numeric keys only, strings/char keys only, arrays of numbers, various objects, or a mix of any of these types/classes as keys?

It's puzzling that you're even asking the question. Maybe you have a strange definition of a look-up-table. In any language, a look-up-table is just an array of whatever things you want to look up. Therefore, in matlab, a lut is simply your standard array if whatever it is to store in your table is homogeneous and scalar, and a cell array otherwise.

 %lut of 60 numbers
 lut = randi(100, 1, 60);
 value = lut(10);  %get lut value corresponding to index 10

%lut of char arrays:
lut = {'the', 'quick', 'brown', 'fox', 'jumps', 'over', 'the', 'lazy', 'dog'}
value = lut(7);  %get lut value corresponding to index 7
