mat
Element
Element functions can be customized with set and show rules.
set and show rules.A matrix.
The elements of a row should be separated by commas, while the rows themselves should be separated by semicolons. The semicolon syntax merges preceding arguments separated by commas into an array. You can also use this special syntax of math function calls to define custom functions that take 2D data.
Content in cells that are in the same row can be aligned with the & symbol.
Example
$ mat(
1, 2, ..., 10;
2, 2, ..., 10;
dots.v, dots.v, dots.down, dots.v;
10, 10, ..., 10;
) $
Parameters
Parameters are the inputs to a function. They are specified in parentheses after the function name.
delim
The delimiter to use.
-
"("Delimit with parentheses.
-
"["Delimit with brackets.
-
"{"Delimit with curly braces.
-
"|"Delimit with vertical bars.
-
"||"Delimit with double vertical bars.
Default:"("

#set math.mat(delim: "[")
$ mat(1, 2; 3, 4) $
augment
Settable
Settable parameters can be customized for all following uses of the function with a set rule.
set rule.Draws augmentation lines in a matrix.
none: No lines are drawn.- A single number: A vertical augmentation line is drawn after the specified column number. Negative numbers start from the end.
- A dictionary: With a dictionary, multiple augmentation lines can be
drawn both horizontally and vertically. Additionally, the style of the
lines can be set. The dictionary can contain the following keys:
hline: The offsets at which horizontal lines should be drawn. For example, an offset of2would result in a horizontal line being drawn after the second row of the matrix. Accepts either an integer for a single line, or an array of integers for multiple lines. Like for a single number, negative numbers start from the end.vline: The offsets at which vertical lines should be drawn. For example, an offset of2would result in a vertical line being drawn after the second column of the matrix. Accepts either an integer for a single line, or an array of integers for multiple lines. Like for a single number, negative numbers start from the end.stroke: How to stroke the line. If set toauto, takes on a thickness of 0.05em and square line caps.
Default:none

$ mat(1, 0, 1; 0, 1, 2; augment: #2) $
// Equivalent to:
$ mat(1, 0, 1; 0, 1, 2; augment: #(-1)) $
$ mat(0, 0, 0; 1, 1, 1; augment: #(hline: 1, stroke: 2pt + green)) $
gap
Settable
Settable parameters can be customized for all following uses of the function with a set rule.
set rule.The gap between rows and columns.
Default:0pt
View example
#set math.mat(gap: 1em)
$ mat(1, 2; 3, 4) $
row-gap
Settable
Settable parameters can be customized for all following uses of the function with a set rule.
set rule.The gap between rows. Takes precedence over gap.
Default:0.5em
View example
#set math.mat(row-gap: 1em)
$ mat(1, 2; 3, 4) $
column-gap
Settable
Settable parameters can be customized for all following uses of the function with a set rule.
set rule.The gap between columns. Takes precedence over gap.
Default:0.5em

rows
RequiredPositional
Positional parameters are specified in order, without names.
Variadic
Variadic parameters can be specified multiple times.
An array of arrays with the rows of the matrix.

#let data = ((1, 2, 3), (4, 5, 6))
#let matrix = math.mat(..data)
