enumerate all possible combinations of an input space

2 views (last 30 days)
for example I have 3 categorical variable, X1 can be 'A,B,or C', X2 can be 'A or D', X3 can be 'E or F', so there can be 3X2X2 different possible combinations:
AAE,AAF, ADE,ADF,BAE,BAF,BDE,BDF,CAE,CAF,CDE,CDF.
which function sould I use to create such a complete list?

X1 = categorical({'A', 'B', 'C'})
X1 = 1×3 categorical array
A B C
X2 = categorical({'A', 'D'})
X2 = 1×2 categorical array
A D
X3 = categorical({'E', 'F'})
X3 = 1×2 categorical array
E F
[X1g, X2g, X3g] = ndgrid(X1, X2, X3);
output = [X1g(:), X2g(:), X3g(:)]
output = 12×3 categorical array
A A E B A E C A E A D E B D E C D E A A F B A F C A F A D F B D F C D F
