TitleDefine and document numeric values as variables before using them in an expression.
PriorityStrongly recommended
Severity level5
DescriptionDo not use magic numbers in your expression. Define them as variables before using them.
RationaleThis encourages reuse and documentation of numerical constants and improves overall readability. As an exception, unit conversion (for example, multiplying by 1e6) can be directly applied.

Avoid:

for iPick = 1 : 52
    disp(randi(13));
end

Instead use:

DECK_SIZE   = 52;
N_VALUES    = 13;

for iPick = 1 : DECK_SIZE
    disp(randi(N_VALUES));
end
