Is there any instruction can ignore the "0" value and find the minimum value of a matrix ?

Is there any instruction can ignore the "0" value and find the minimum value of a matrix ? I mean ,if i assume

A=[0 1 2 3]

How do i write the code to let the minimum value is 1 instead of 0

[Stephen23]

>> min(A(A>0))
ans = 1

Answer 1

A=[0 1 2 3]
[val,idx] = sort(A) ;
iwant = val(2)

A(A==0) = NaN
min(A)
