I have the following code with multiple conditional statements . Could someone suggest if there is a consice way of writing the same code? I'm looking for suggestions that can simply the if- elseif statements.

 Number = 1:10
    Value = [1 2 2 3 1 4 4 5 2 3]
    UniqueValue = unique(Value)
    for Num = Number
    Val = Value(Num)    
    if Val == UniqueValue(1)
       disp(Val+Val-1)
    elseif Val == UniqueValue(2)
       disp(Val+Val-1)
    elseif Val == UniqueValue(3)
       disp(Val+Val-1)
    elseif Val == UniqueValue(4)
       disp(Val+Val-1)
    else
       disp(Val+Val-1)
    end
    end

Looks like I was too late. ;-) You came to the same conclusion by the time I finished writing my response.

You've answered your specific question, but if you encounter similar code constructs in the future (needing to check whether something is a member of a finite set of options without a potentially long series of nested if / elseif / else statements) consider ismember (as Rik suggested) or a switch / case statement.
