What is the equivalence for the Big M in MATLAB?

Hi, If I want to assign a really big number to a matrix so that when I want to take the minimum of the vector then that element is never chosen what should I do? In math we usually use the Big M in consitraints which stands for a really big number.

Sounds like you want Inf (infinity)

% Inf is not the minimum of the vector, as long as there 
% are some finite number (non-Inf and non-NaN) elements
min([1 2 Inf 4])

ans = 1

min([NaN NaN Inf NaN])

ans = Inf
