Why sometimes we place an empty brackets inside function inputs?

I don't know the purpose or the mean of these empty square brakets inside many functions, for instance:

min( a, [ ],2)

imshow(a, [ ])

[JESUS DAVID ARIZA ROYETH]

means that the second value the function receives is empty, in both cases

if you give a value to that second parameter to "min" the function will convert the largest values of "a" into the value you assign to that parameter
