16 giu 2018 · Off-topic: instead of providing lots of empty columns (presumably to increase the separation between "real" columns, right?), it would be much more efficient if you (a) replaced all instances of && with & and (b) issued the command \setlength\arraycolsep{10pt}.
5 mar 2013 · The amsmath package also offers the shortcut matrix environments which default to centered alignment for their columns: matrix: unbracketed matrix; pmatrix: matrix surrounded by parentheses; bmatrix: matrix surrounded by square brackets; vmatrix: matrix surrounded by single vertical lines; Vmatrix: matrix surrounded by double vertical lines

29 ago 2015 · I'm a new user in texmaker. How can I produce this equation? Thank you for your help
3 set 2016 · I suggest you load the amsmath package, employ its the bmatrix ("bracketed matrix") environment, and use \dots (or \ldots), \vdots ("vertical dots"), and \ddots ("diagonal dots") as needed. The following screenshot shows two ways this approach could be employed. The first replicates the matrix shown in the OP's posting.

I am new to Latex, and I have been trying to get the matrix of following form [x11 x12 x13 . . . . x1n x21 x22 x23 . . . . x2n .
The matrix environments of the amsmath and mathtools environments work with the counter variable MaxMatrixCols. Its default value is 10; if you have a matrix with, say, 15 columns, issue the instruction \setcounter{MaxMatrixCols}{15}. There is no \fract command; use \frac instead. For the matrix at hand, I actually wouldn't use any \frac ...
