MATLAB Functions and Variables

CHENNAI, India - May 23, 2014 - PRLog -- MATLAB is a programming language used specifically for numerical computations, signal processing and it’s a graphical user interface programming. MATLAB is faster in performing complex computations when compared to traditional programming languages such as Java, C, C++, etc.

Applications

·   Signal processing

·   Image processing

·    Financial modelling and analysis, etc.

Add-on toolboxes

MATLAB contains several functions, operators and variables inbuilt within it. Here are some of the functions and variables listed below:-

Function Syntax

function [y1,...,yN] = myfun(x1,...,xM)

Here x1,x2….xM are the inputs and y1,…,yn are the outputs in the function.

The file is saved with .m extension. The file name and name of the first function should match the same. If nested functions are used, then end keyword must be used.

Syntax of variables

varargin

This is an input variable and usually variables are declared in lowercase letters. This variable is used to refer a 1-by-N cell array.

There are several graphical elements namely,

·   2-D and 3-D slots

·   Graphical objects

·    Images

·    Visualization methods

MATLAB Operators

Operators are used to perform arithmetic, relational and logical operations. Here are some of them listed below:-

(Arithmetic)Plus, uplus, minus, uminus, (Relational) eq, ge,gt,le, (logical)and,not,or,xor, (bitwise operator) bitand, bitcmp,bitget and many more.
