Library: Math: Matrix

» What's the Objective?

Matrices are collection of variables represented in tabular format (Rows & Columns). Often we've have to deal with multiple coordinates when either dealing with general or complex mathematics; Matrices do help a lot to make the workflow easier in such scenarios. Moreover they are also widely used in games for representing element's positional/rotational matrix.

If you still have no idea how useful they are or where to apply/utilize them in the right way, then make sure to read: https://personalpages.manchester.ac.uk/staff/ctdodson/matrices.pdf

» How to Import?

It gets imported automatically by default whenever you initialize assetify.

--Declare it globally only once
loadstring(exports.assetify_library:import())()

» Operations

Addition

local cMatrix1, cMatrix2 = math.matrix({1, 1, 1, 1}, {1, 1, 1, 1}), math.matrix({2, 2, 2, 2}, {2, 2, 2, 2})
local resultant = cMatrix1 + cMatrix2

Subtraction

local cMatrix1, cMatrix2 = math.matrix({1, 1, 1, 1}, {1, 1, 1, 1}), math.matrix({2, 2, 2, 2}, {2, 2, 2, 2})
local resultant = cMatrix1 - cMatrix2

Multiplication

local cMatrix1, cMatrix2 = math.matrix({1, 1, 1, 1}, {1, 1, 1, 1}), math.matrix({2, 2, 2, 2}, {2, 2, 2, 2})
local resultant = cMatrix1 * cMatrix2

Division

local cMatrix1, cMatrix2 = math.matrix({1, 1, 1, 1}, {1, 1, 1, 1}), math.matrix({2, 2, 2, 2}, {2, 2, 2, 2})
local resultant = cMatrix1 / cMatrix2
