converting values from conditional to single equation

Hi all

I need to convert this if condition to one equation

let's assume we have this if statment

    if x>=0
        f = x(i);
    else
        f = 0.2*(exp(x)-1);
    end

can I re-write if statment in one equation ?

Any suggestion would be appreciated

One possibility

f = x(i)*(x(i)>=0) + 0.2*(exp(x(i)) - 1)*(x(i)<0);
