Matrix with vertical line (absolute line or determinant matrix). Incidentally, I have found that if I use a formula containing the above glyphs in a section title, LaTeX gives error messages, and refuses to continue until I hit carriage-returns but that if \newcommand is replaced by \DeclareRobustCommand in both the above definitions, the problem goes away. Sixnewcommands arede nedforrepresentingvectorswithasingle(possiblycomposite)symbol. The mathtools usepackage also offers adaptations for the matrices in the continuous text.
In the case that a matrix is desired in which different columns have a different alignment, this can be realized via the array environment. However, it must be said that only all columns can be aligned uniformly. The desired orientation is passed as options r (right justified), c (centered) or l (left justified). The structure corresponds to the environments from amsmath, but the names of the environments have an additional star at the end. It is now possible to use right-aligned or left-aligned columns within the matrix environments. The mathtools usepackage extends the amsmath usepackage's matrix environments with the ability to set column alignment. The symbols in brackets must be a printable character or, if it is a special character like the braces \bigr)$ is only for showing.įor the omissions there is a new command hdotsfor with which at least horizontal dots can be set. The parentheses can be inserted with the commands left and right, as the following examples show. In this simple example you can already see the problem with parentheses and that the columns have to be defined in advance. As an example for the representation of matrices the unit matrix is used here, since its structure might be generally known. bmatrix for square brackets, vmatrix for vertical lines, Vmatrix for double. This must be set additionally around the matrix. a label, I used the notag command in the. On the other hand, the array environment lacks the typical parenthesis that encloses a matrix. But two things have to be considered, firstly the number and the alignment of the columns have to be defined and set in advance.
Here you have to use the array environment if you want to set a matrix or a vector. However, within the standard there is no separate command or environment for this. In the following commands and possibilities for the representation of matrices and vectors in LaTeX are shown. Within LaTeX there are several ways to set matrices and vectors.
