Plotting File data:
It is frequently essential to read data from a file and plot it. Generally, this entails knowing the format of the file. For illustration, let us suppose that a company has two divisions, called A &B. The file 'ab06.dat' has 4 lines in it (we will suppose this), with the sales figures in millions for the two divisions for each quarter of the year 2006. For illustration, the file may appear like this (the format will be precisely like this):
A5.2B6.4
A3.2B5.5
A4.4B4.3
A4.5B2.2
The script below reads the data and plots in one Figure Window the data as the bar charts. The script prints an error message when the file open is not successful or when the file close was unsuccessful. The axis command is used to force the x-axis to range from 0 to 3 and the y-axis from 0 to 8 that will result in the axes shown here. The numbers 1 and 2 would display on the x-axis instead of the division labels A and B by default. The set function modifies the XTickLabel property to use the strings in the cell array as labels on the tick marks on the
x-axis; and gca returns the handle to the axes in the present figure (it stands for "get present axes").
Running this generates the subplot as shown in figure.
Changing Case: The MATLAB has two functions which convert strings to all uppercase letters, or all lowercase, known as the upper and lower. >> mystring = 'AbCDEfgh';
Anonymous Functions: The anonymous function is a very easy, one-line function. The benefit of an anonymous function is that it does not have to be stored in an M-file. This ca
Appending variables to the Mat-File: Appending to the file adds to what has been saved in a file, and is accomplished by using the -append option. For illustration, supposing
analyzing traffic; determine motion of flow; calculate tracklets; detect abnormalities;
Modular programs: In a modular program, the answer is broken down into modules, and each is executed as a function. The script is usually known as the main program. In orde
Illustration of Sound files: For illustration, the following script generates a subplot which shows the signals from chirp and from train, which is as shown in figure:
Illustration sorting vectors of structures: This function sorts the structures depend only on the price field. A more common function is shown next, that receives a string whi
Matrix Multiplication: The Matrix multiplication does not mean multiplying term by term; and it is not an array operation. The Matrix multiplication has a very particular mean
