Matrix IIF 1.0

iif(Cond, ExprA,ExprB) is inspired in a traditional function from Visual Basic that receives a condition and returns ExprA or ExprB, depending of COND evaluation (true or false)As MatLab is a matrix language, iif was implemented as a matrix function.Suppose that COND compares a matrix with a number so COND is a matrix of same dimensions. The matrix result contains just A or B elements, depending if COND is true ("A") or false ("B")Example:A = [ 1 5 8 3 ];disp( iff(A > 4, 100,-200) )The display is [ -200 100 100 -200 ]Normally it can be done of a less intuitive way (the method that iif was internally implemented) A = (A>4)*100 + (AB,(2*A+B)/3, (2*B+A)/3))Result is [6.66 7.66 5.66 7.33]The alternative way is (and the form that was internally implemented) (A>B).*(2*A+B)/3 + (A
