I have an array A. A1= [-0.0082 -0.0409 -0.0175 -0.0853 0.0217 -0.2556 -0.0302 0 ]
From A array I want to replace negative numbers with -1, positive numbers with 1 and zero will remain zero . Like this :
A= [-1 -1 -1 -1 1 -1 -1 0]
Then I want to take there sum and if there sum is smaller than threshold then value will be set to zero. If equals and greater than threshold than value will be 1. Threshold is 12.
How to write code for this?

A1 = [-0.0082 -0.0409 -0.0175 -0.0853 0.0217 -0.2556 -0.0302]
A = -(A1<0) + (A1>0)
s = sum(A)
threshold = 12;
value = double(s >= threshold)

0 and -0 display as 0 not as 0.0000 or -0.0000. So your values are not 0 and -0
Give the command
format long g
and then display your values again
