Question: how to use "brackets" for several lines

hello how do i use bracekt for several lines, like in this picture I need to write this in maple.

i already know how to setup matrices for nX1 or 1Xn (as in vector) or multiples such as

nXn (square matrice) or nXm (a none square matrice)

I also know that we have this premade "sketch"

but I need for several line and some times I need on the right side and some time I need on the left side.

but rarely on both sides (and if I need on both side I will just use a matrice)

can you help me
