As an input for an equation or a function I want to make a row of inputvalues. The only value that they can have is -1 and +1. They have to be in random order. I tried to make uniform distribution between 0 and 1. I thought that it had to be possible to change the values which are > 0.5 to 1 and al the other values to -1.
How can I use an if-else statement in a vector to get this done or can it be done in an other way?
