Meaning of square bracket

x(2,:)=[];

Answer 1

[John D'Errico]

You probably need to do the basic MATLAB onramp tutorial, as this should be covered there. And it is free.

But this is how you can delete an element, or in this case the second row of the array x.

x = magic(4)

x = 4×4

16 2 3 13 5 11 10 8 9 7 6 12 4 14 15 1

x(2,:) = []

x = 3×4

16 2 3 13 9 7 6 12 4 14 15 1
