Eq

We can compare two matrices with the == operator. One needs to be careful though as matrices stored as tables + meta methods are always different from matrices stored as user date. Comparison is done element by element.

Example.Quanty

A = Matrix.New({{1,2},{3,4}})
B = Matrix.New({{1,2},{3,4}})
C = Matrix.New({{5,6},{7,8}})
 
D = {{1,2},{3,4}}
setmetatable(D, MatrixMeta)
E = {{1,2},{3,4}}
setmetatable(E, MatrixMeta)
F = {{5,6},{7,8}}
setmetatable(F, MatrixMeta)
 
print("Matrix as Userdata comparison")
print("A==B ",A==B)
print("A==C", A==C)
print("Matrix as table with metadata comparison")
print("D==E ",D==E)
print("D==F", D==F)
print("but WARNING WARNING, userdata are never equal to tables with metadata")
print("A==D", A==D)

Matrix as Userdata comparison
A==B 	true
A==C	false
Matrix as table with metadata comparison
D==E 	true
D==F	false
but WARNING WARNING, userdata are never equal to tables with metadata
A==D	false
