Aim:

To understand the basic logic behind Matrices and its Operations using Matlab tool.

Softwares Reqire!:

Matlab R2015a

"ar!ware Reqire!:

A personnel Computer.

Pro#e!res:

1. Open matlab File.

2. Type the program in the editor indo.!. "a#e the $ile ith .m %&tension and run

the program.

'. (eri$y the output in the command )indo.

T$eor%:

Arrays are container ob*ects $or storing data. +n

contrast to tables, the indices must be se-uences o$

integers. )hile tables may gro in sie dynamically,

the number o$ entries in an array created by array is$i&ed.

A "calar is a /1 & 1 Matri& containing single

element only. A column #ector is an /m & 1 matri& that

has m number o$ ros but single Column only. A

Ro #ector is an /1 & n matri& that has n number o$

columns but single ro only.

A 1dimensional array is printed as a ro #ector. The

inde& corresponds to the column number.

A 2dimensional array is printed as a matri&. The $irst

inde& corresponds to the ro number and the second

inde& corresponds to the column number.

Array Operations

% Assigning array

elements row wise to a

variable A

% Assigning array

elements row wise to avariable B

% Adding elements in A

with B

% ubtracting elements

in A from B

% !ultiplying elements

in A with B ("lement by

"lement)

% #ividing elements in A

with B ("lement by

"lement)
