Email: [email protected] In Algebra, Division of matrices is done by Inverse-Multiplication Divisor Matrix with Dividend Matrix. There are two different methods are possible to divide two square or rectangular matrices. The Probability of Matrices Division is 0.5 plus. The overall concept of this paper is Division of Matrices is possible. Key Words: Law Matrices Multiplication[a]; Slash and Back Slash Matrices/Mirror Image Matrix[b]; Matrices Commutative Law[c]. Matrix Digonalization[d]; Product Matrix[e]
1. Introduction
Let us consider Two matrices J and K having m number of rows and n number of columns and the product of matrices J and K is S

m = n for Square matrices
The product of matrices J and K is matrix-S called Product Matrix[d]
(i.e., jn = km)

General Condition to divide two matrices
1. Determinant of Divisor Should not be Zero (i.e., |A|/|B| = element-c. |B| ≠ 0 ) 2. Either divisor row/column must be equal to dividend row/column

Proof: for condition -2
Multiplicand is unknown i.e., [J] is unknown.
To find order matrix –J = [ J ]
[ J ] = [ S ] / [ K ]
JM X JN = (SM X SN) / (KM X KN) = (JM X KN) / (KM X
KN)
In this case Dividend and Divisor columns must be
Equal to get Quotient (i.e.,[ J ]).
The order of Quotient matrix is
dividend row x divisor row
Multiplier is unknown i.e., [ K ] is unknown.
To find order matrix –K =[ K ]
[ K ] = [ S ]/[ J ]
KM X KN= (SM X SN) / (JM X JN) = (JM X KN) / (JM X
JN)
In this case Dividend and Divisor rows must be Equal
to get Quotient(i.e.,[ K ]).
The order of Quotient matrix is
divisor column x dividend column
2. Methods
i) Determinants ii) Solving Linear Equations
Method 2.i. used for Square matrices (i.e., m = n) and method 2.ii. Is used for both Rectangular and Square matrices
2.i. Division by Determinants
Rows of Matrices J,K and S are equal to the Columns of Matrices J,K and S
This method is based on Cramer’s Rule
Jm = Jn : Km = Kn : Sm = Sn
2.i.a. When Rows of Dividend & Divisor are Equal the elements of [ J ]
퐉퐬퐦, 퐬퐦 → 퐤퐦 = [푲]풔풎,풔풎 → 풌풎− −−− −−−
[푲]풌풎,풌풏 … ( 풊풊 )
Here sm→km means, Substituting/Replacing mth row of
[S] in mth row of [K]
( Determinant of replaced or substituted matrix by rows
) / ( Determinant of actual/original/primary matrix )
2.i.b when Columns of Dividend & Divisor are Equal
the elements of [ K ]
퐊퐬퐧 → 퐣퐧, 퐬퐧 =[푱]풔풏 → 풋풏, 풔풏−−− −− −−
[푱]풋풎, 풋풏 … . ( 풊풊풊 )
Here sm→jn means by Substituting/Replacing nth
column of [S] in nth column of [J]
(Determinant of replaced or substituted matrix by
column) / (Determinant of actual/original/primary
matrix)

2.ii. Division by solving Linear equations
Rows of Matrices J,K and S are not equal to the Columns of Matrices J,K and S
Jm ≠ Jn : Km ≠ Kn : Sm ≠ Sn
This method is based on Gauss Seidel method

property and λ (Eigen value column matrix) is same
But Eigen Vector are Different because elements of Both [ A ][ A. ] are not same i.e., [ x ] ≠ [ y ]

Linear Equations are 3X1 + 5X2 = 26 1X1 + 6X2 = 26 [ X1 X2 ] = [ 2 4 ]
i) Assuming Matrix-B is unknown ( bm x bn ) = [ C ] / [ A ] = (1 x 2) / ( 1 x 2) Row and Columns are Equal
Rows are equal bm x bn = Divisor column X Dividend column = ( 2 x 2 ) [ 2 4 ] 풙ퟏ 풙ퟐ
풙ퟑ 풙ퟒ =[ 26 26 ] 2.x1 + 4.x3 = 26 2x2 + 4.x4 = 26 x1 = ( 26 – 4 x3) / 2 & x2 = ( 26 – 4 x4) / 2
Columns are equal i.e., bm x bn = Dividend row X Divisor Row = (1x1) This is not correct because 2X=26 and 4X=26 X value cannot be same for both equations. Final answer is ( bm x bn) = (2x2) 5. IMPORTANT NOTES Note 1: Wrong Matrix Division gives wrong Quotient
(this is possible only in case of Square Matrices).
Note 2: This method is applicable for Rectangular matrices too if Determinant of Rectangular matrix is calculatable. Note 3: In both methods and both cases, Wrong Assumptions of Rows and Columns give Wrong Quotient Matrix which is Mirror Image Matrix clearly Note 4: Accurate matrices division is possible in Rectangular matrices only. Note 5: It is possible to create matrices like AB=BC where A≠C
Note 7: for Commutative Matrices (The matrices which satisfies Commutative Law) Division is possible by Methods and Both assumptions (i.e., Rows are Equal and columns are Equal).
Commutative Matrices: [ A ] [ B ] = [ B ] [ A] = [ C ] Where matrix – B equals to
i) [ B ] = [ A ] ii) [ B ] = [ A-1 ] iii) [ B ] = [ I ] iv) [ B ]=[ S ],Where [ S ] is a Diagonal
Matrix v) [ B ] = [ X ],Where [ X ] is Commutative
matrix to matrix [ A ]
i, ii, iii and iv always satisfies Commutative law [ A ] [ B ] = [ B ] [ A ]
For iv condition [ A ] [ B ] = [ B ] [A ] where [ B ] = [ X ], [ X ] is Commutative matrix to matrix [ A ]
6 CONCLUSION
In Matrices Division determinant Divisor must not be zero to divide two matrices. Division of Square matrices gives Mirror Image Matrix Which should obey the all the properties like Determinant, Trace, Law of Matrix Multiplication and Digonalization of Mirror image Matrix. Mirror Image matrix is also called as Pseudo or Slash Matrix. The main aim of these methods is to prove everything is possible in Mathematics and Physics with Equations to analyze the system. This Methods are based on Cramer’s Rule ( Substitution of column and also Rows ) and Gauss – Seidel Method ( to solve linear equations ). The Accuracy is 100% in Both cases but generates Mirror Image Matrices User has to select which one is suitable. The Time taken to calculate Real and Mirror Image Matrices is More and Memory Required to Calculate Both Matrices is More. For Commutative matrices both real and mirror image matrices are same.
