MATLAB: Create a vector without for

Question

The vector structure is like [a b c d e f g h i j]

a=1:10

b=1:10

…

j=1:5

vect=[]

I can use for a =1:10

for b=1:10

…

vect = [vect;a.b…j]

end

end

but it looks not elegant. Is there a better way to generate it?

Answer 1

a=1:10;
b=1:10;
c=1:3;
d=1:5;
[A, B, C, D] = ndgrid(uint8(a), uint8(b), uint8(c), uint8(d)) ;
v = [A(:), B(:), C(:), D(:)] ;
