__Multiplication of two Matrices:-__There are two type of multiplication that we can performed in MATLAB

**1.Multiplication of two Matrices in normal way:**

A=B*C;

**2.Multiplication of each elements of first matrix with corresponding**

**elements of second matrix:**

A=B.*C;

it use

**" . "**before " * ". for thsi operation no. of elements should be same in both matices.

Similarly we can perform

**Division**operation.

__Some Mathematical Operations & Their Instructions:-__

Addition

**A=B+C;**

Subtraction

**A=B-C;**

Multiplication

**A=B*C; or A=B.*C;**

Division

**A=B/C; or A=B./C; or A=B\C; or A=B.\C;**

**(A=B\C=C/B)**

Transpose

**B=A';**

Power

**B=A.^C; or A.^2**(this operation always performed with "

**.**").

Sum of All Elements of A Matrix

**X=sum(A);**

Diagonal elements of any matrix

**Y=diag(A);**

max no. in any matrix

**M=max(A);**

**shortest no. in any matrix**

**S=short(A);**

Average

**A=avg(B);**

**Trigonometric Operations**

Sine

**A=sin(B);**

Cosine

**A=cos(B);**

Sine Inverse

**A=asine(B);**
