Logical operator not evaluating correctly
显示 更早的评论
Given the provided array X, create an array Y that is:
equal to 0 if the corresponding element of X is between -5 and +5, inclusive
equal to -1 if the corresponding element of X is less than -5
equalt to +1 if the corresponding element of X is greater than 5
Here is what I have:
Y = (~(X >= -5 & X <= 5) | (-1*(X < -5)) | (X>5)).
Why is the X < -5 not evaluationg to -1?

Only two comparisons are actually required here —
X = linspace(-7, 7, 15);
Y = -(X < -5) + (X > 5);
Check_Result = [X; Y]
.

A|B is an or test and returns a logical value -1 is nonzero which is considered true, and since you or everything together you are going to end up with logical true for those entries.
Try adding the results of the computation
I would do this in separate steps.
X = randi([-20, 20], [1 15])
Y = zeros(size(X));
Y(X < -5) = -1;
Y(X > 5) = 1
