I want to create a matrix with entries -1, 0, and 1 but it gives only -1 and 1, how to adjust
x = [9 3.6 9; 11 3.6 9; 9 4.4 9; 11 4.4 9; 9 3.6 11; 11 3.6 11;9 4.4 11; 11 4.4 11];
% convertion to -1, 0, and 1
V = ( x(:,1) - min(x(:,1)) )/(range(x(:,1))/2) - 1; %% This line needs some modifications
% NOW convert to MATRIX (-1. 0, and 1)
% Below lines also need some modifications
X = [(x(:,1) - min(x(:,1)))/1 - 1 (x(:,2) - min(x(:,2)))/0.4 - 1 (x(:,3) - min(x(:,3)))/1 - 1]
X = 8×3
-1.0000 -1.0000 -1.0000 1.0000 -1.0000 -1.0000 -1.0000 1.0000 -1.0000 1.0000 1.0000 -1.0000 -1.0000 -1.0000 1.0000 1.0000 -1.0000 1.0000 -1.0000 1.0000 1.0000 1.0000 1.0000 1.0000

like the output of,
dBB = bbdesign(3)
%% Can be found in https://in.mathworks.com/help/stats/bbdesign.html

Perhaps this is what you had in mind?
x = [9 3.6 9; 11 3.6 9; 9 4.4 9; 11 4.4 9; 9 3.6 11; 11 3.6 11;9 4.4 11; 11 4.4 11];
X=rescale(x,-1,1,InputMin=min(x,[],2), InputMax=max(x,[],2) )
X = 8×3
1.0000 -1.0000 1.0000 1.0000 -1.0000 0.4595 1.0000 -1.0000 1.0000 1.0000 -1.0000 0.3939 0.4595 -1.0000 1.0000 1.0000 -1.0000 1.0000 0.3939 -1.0000 1.0000 1.0000 -1.0000 1.0000
X(abs(X)<1)=0
X = 8×3
1 -1 1 0 -1 0 1 -1 1 1 -1 0 0 -1 0 0 -1 0 0 -1 1 1 -1 1

Dear Matt
Why here is an option "Moved"? I didnot get that.
