matrix.add_col() - Pine Script Function

`matrix.add_col()`

Overview

Inserts a new column at the column index of the id matrix.

Syntax

matrix.add_col(id, column, array_id) → void

Parameters

Name	Type	Description
id	any matrix type	The matrix object’s ID (reference).

Remarks

Rather than add columns to an empty matrix, it is far more efficient to declare a matrix with explicit dimensions and fill it with values. Adding a column is also much slower than adding a row with the matrix.add_row function.

Examples

Example 1

//@version=6
indicator("`matrix.add_col()` Example 2")
if barstate.islastconfirmedhistory // Create an empty matrix object. var m = matrix.new<int>() // Create an array with values `1` and `3`. var a =
array.from(1, 3) // Add the `a` array as the first column of the empty matrix. matrix.add_col(m, 0, a) // Display matrix elements. var t =
table.new(position.top_right, 2, 2, color.green) table.cell(t, 0, 0, "Matrix elements:") table.cell(t, 0, 1, str.tostring(m))
