Do we have any Fucntion which can generate +1 and -1 randomly????

I am using the following thing to generate it...

a=rand(1,10);

b=round(a);

b( b==0 )=-1;

So is there any other best way to genrate +1 and -1 randomly

I don't think there is any function doing that.

Here is another approach:

sign(rand(1,10)-0.5)

or

(-1).^(round(rand(1,10)))
