I wanted to create a function that consists of a number and functions and works like this
if x<-1 y=-x^2-4*x-2
if |x|<1 y=|x|
if x>1 y=2-e^(sqrt(x-1))

If the function is symbolic, then use piecewise.
help piecewise
Note that your function lacks definition, since you do not say what happens when x==1 or x==-1.
For a general matlab function, you can use my piecewise_eval, it is on the file exchange.
Pretty old now, but it should still work.
I also see many other tools on the FEX that claim to do the job too.
