Programming in MATLAB for Beginners-3

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);
