MATLAB ESSENTIALS FOR BIOMEDICAL ENGINEERS

MATLAB is a very important tool for every engineer but it plays a special role in the life of biomedical engineer so i decided to start up on MATLAB in a totally different fashion

First Steps in MATLAB

First of all officially  “MATLAB is a software package that lets you do mathematics and computation, analyse data, develop algorithms, do simulation and modelling, and produce graphical displays and graphical user interfaces.”

GETTING STARTED IN MATLAB

  1. To run matlab on a PC double-click on the matlab icon.To run matlab on a unix system, type matlab at the prompt.

Biomedical Signal Processing Toolbox-BIOMEDICAL SIGNAL ANALYSIS

Abstract.

This article describes a biomedical signal processing (BSP) toolbox for the analysis
of physiologic signals. The BSP toolbox is designed to enable researchers to conduct
preliminary analysis of physiologic time series, such as the electrocardiogram (ECG),
intracranial pressure (ICP), arterial blood pressure (ABP), and oxygen saturation (SpO2).
The toolbox includes detection algorithms for the ECG and pressure waveforms, spectral
analysis, nonlinear filtering, multi-signal analysis, and nonstationary signal visualization.
The following sections discuss the functionality of this toolbox and provide examples of its
application.

WHAT ARE THE LIMITS OF MATLAB?

LIMITATIONS OF MATLAB

1.)MATLAB is a proprietary product of The MathWorks, so users are subject to vendor lock-in. Some other source languages, however, are partially compatible and provide a migration path.

2.)The language has a mixed heritage with a sometimes erratic syntax. For example, MATLAB uses parentheses, e.g. y = f(x), for both indexing into an array and calling a function. Although this ambiguous syntax can facilitate a switch between a procedure and a lookup table, both of which correspond to mathematical functions, a careful reading of the code may be required to establish the intent.

WHAT IS THE MATLAB???

MATLAB is a numerical computing environment and programming language. Created by The MathWorks.

FUNCTIONS OF MATLAB

  • easy matrix manipulation,
  • plotting of functions and data implementation of algorithm
  • creation of user interfaces,
  • implementation of algorithms,

HISTORY OF MATLAB

Short for “matrix laboratory”, MATLAB was invented in the late 1970s by Cleve Moler, then chairman of the computer science department at the University of New Mexico. He designed it to give his students access to LINPACK and EISPACK without having to learn Fortran. It soon spread to other universities and found a strong audience within the applied mathematics community.
