What are the functions of MATLAB?
- MATLAB Function Example Handout. MatLab is a high performance numeric computing environment, which includes numerical analysis, matrix computation, signal processing, and graphics to provide answers to the most troubling of mathematical problems. This handout provides different examples to show the different aspects of MatLab.
How to generate unit step function in MATLAB?
- function [x]=unitstep (x) %This is a unit step "function". The vector keeping track of time is the %input. If time is negative then a zero is returned. If time is zero than %0.5 is returned.
How to generate square wave in MATLAB?
- Square wave is generated using “square” function in Matlab. The command sytax – square (t,dutyCycle) – generates a square wave with period for the given time base. The command behaves similar to “ sin ” command (used for generating sine waves), but in this case it generates a square wave instead of a sine wave.
