matrix.remove_row() - Pine Script Function

`matrix.remove_row()`

Overview

The function removes the row at row index of the id matrix and returns an array containing the removed row’s values.

Syntax

matrix.remove_row(id, row) → array<type>

Parameters

Name	Type	Description
id	any matrix type	A matrix object.

Returns

An array containing the elements of the row removed from the id matrix.

Remarks

Indexing of rows and columns starts at zero. It is far more efficient to declare matrices with explicit dimensions than to build them by adding or removing rows.

Examples

Example 1

//@version=6
indicator("matrix_remove_row", overlay = true)// Create a 2x2 "int" matrix containing values `1`.var matrixOrig = matrix.new<int>(2, 2, 1)// Set values to the 'matrixOrig' matrix.matrix.set(matrixOrig, 0, 1, 2)
matrix.set(matrixOrig, 1, 0, 3)
matrix.set(matrixOrig, 1, 1, 4)// Create a copy of the 'matrixOrig' matrix.matrixCopy = matrix.copy(matrixOrig)// Remove the first row from the matrix `matrixCopy`.arr = matrix.remove_row(matrixCopy, 0)// Display matrix elements.
if barstate.islastconfirmedhistory
var t = table.new(position.top_right, 3, 2, color.green)
table.cell(t, 0, 0, "Original Matrix:")
table.cell(t, 0, 1, str.tostring(matrixOrig))
table.cell(t, 1, 0, "Removed Elements:")
table.cell(t, 1, 1, str.tostring(arr))
table.cell(t, 2, 0, "Result Matrix:")
table.cell(t, 2, 1, str.tostring(matrixCopy))
