matrix.inv() - Pine Script Function

`matrix.inv()`

Overview

The function returns the inverse of a square matrix.

Syntax

matrix.inv(id) → matrix<float>

Parameters

Name	Type	Description
id	matrix<int/float>	A matrix object.

Returns

A new matrix, which is the inverse of the id matrix.

Remarks

The function is calculated using the LU decomposition algorithm.

Examples

Example 1

//@version=6
indicator("`matrix.inv()` Example")// For efficiency, execute this code only once.
if barstate.islastconfirmedhistory // Create a 2x2 matrix.
var m1 = matrix.new<int>(2, 2, na) // Fill the matrix with values. matrix.set(m1, 0, 0, 1)
matrix.set(m1, 0, 1, 2)
matrix.set(m1, 1, 0, 3)
matrix.set(m1, 1, 1, 4) // Inverse of the matrix.
var m2 = matrix.inv(m1) // Display matrix elements.
var t = table.new(position.top_right, 2, 2, color.green)
table.cell(t, 0, 0, "Original Matrix:")
table.cell(t, 0, 1, str.tostring(m1))
table.cell(t, 1, 0, "Inverse matrix:")
table.cell(t, 1, 1, str.tostring(m2))
