Matlab Codings

Matlab is a number of commercially available, sophisticated mathematical computation tools. Matlab coding is used for both computer programming language and software environment.

Need of Matlab Codings: Below are four main reasons for need of Matlab codings. 

 

4 Reasons Why do u need Matlab Coding?

 

1.Fast implementation of vector or matrix operations.

2.Powerful Visualizations.

3.Capability to work with simulation environment because have huge library of mathematical functions and algorithms.

4.Matlab built-in functions are used for computations, graphics and external interfaces.

 

Process of Plotting Graph Using Matlab Codings:

1.Interactive tools allows to manipulate graphs to achieve results

2.Matlab environment should provides a wide variety of techniques to display data graphically

3.Annotate and print graphs for presentations or export graphs in web browser or other media

 

Matlab Codings

M-Files:

1.M-Files can be the scripts or functions

2.Functions make use of their own local variables and accept input arguments

3.Scripts are usually called as simple files containing a sequence of matlab statements 

Order Precedence of Matlab Codings:

1.Parentheses.

2.Exponentiation.

3.Multiplication and Division.

4.Addition and Subtraction.

MATLAB CODINGS FOR BINARIZATION:
clear;
close all;
im1=imread(‘page.png’);
im2=imread(‘tshape.png’);
bwim1=adaptivethreshold(im1,11,0.03,0);
bwim2=adaptivethreshold(im2,15,0.02,0);
subplot(2,2,1);
imshow(im1);
subplot(2,2,2);
imshow(bwim1);
subplot(2,2,3);
imshow(im2);
subplot(2,2,4);
imshow(bwim2);

Matlab Functions: Matlab should more helpful for both real and complex data making . Complex computation is very easy., Editor Window,GUI (Graphical User Interface)., Command Window ,Figure Window are the type of windows used in matlab codings

MATLAB CODINGS FOR VISUALIZE DATA:
Visualize 4D Data with One Discrete Variable
Load patients Smoker Age Weight Systolic % load data
nsIdx = Smoker ==0;
smIdx = Smoker ==1;
figure
stem3 (Age (nsIdx), Weight (nsIdx), Systolic (nsIdx), ‘Color’, ‘b’) % stem plot for non-smokers
hold on
stem3 (Age (smIdx), Weight (smIdx), ‘Color’, ‘r’) % stem plot for smokers
hold off
view (-60, 15)
zlim ([100 140])
xlabel (‘Age’)
ylabel (‘Weight’) % add labels and a legend
zlabel (‘Systolic Blood Pressure’)
legend (‘Non-Smoker’, ‘Smoker’, ‘Location’, NorthWest’)
