How to type in v1 = +/- w2/((w3^2)+(w2^2)) and v2 = +/- w3/((w3^2)+(w2^2))?
The problem is that the vectors can be both positive and negative

Is this in the context of symbolic variables? Otherwise Matlab numeric arrays must have a definite value.

If it is the data itself that is positive or negative, then that is reflected in the values themselves.
If the sign of the terms in the equations themselves are to be different, then you have to code those explicitly and evalute the one of choice. Or, alternatively, code in another coefficient in the location of the sign and set that as data to plus/minus one.
