elements in a matrix

[popo123]

Hi,

I have a matrix A=[2 1 -1;-1 5 -2;-2 -4 -5;1 2 3], and I would like to determine the every element in A in LabVIEW. If the element is 

greater or equal to zero, I will change the element to 1. Otherwise, the element is changed by -1. In other words, the new matrix should be B=[1 1 -1;-1 1 -1;-1 -1 -1;1 1 1] based on the rules before. Does anyone help me?

Thanks,

POPo

If you don't really care about zero, use the Sign function from the numeric palette, else add a little more code. 🙂

If you don't want zeroes in the output (as originally specified), you could do as follows:
