For example, to con ne the vertical range to the interval from 1 to 4, type >> axis([-2 2 1 4]) The rst two numbers are the range of the horizontal axis; both ranges must. 2: MATLAB Basics be included, even if only o .net framework qr bidimensional barcode ne is changed. We ll examine more options for manipulating graphs in 5.

To close the graphics window select File : Close from its menu bar, type close in the Command Window, or kill the window the way you would close any other window on your computer screen.. Graphing with plot The command plot works on v QR Code ISO/IEC18004 for .NET ectors of numerical data. The basic syntax is plot(X, Y) where X and Y are vectors of the same length.

For example,. >> X = [1 2 3]; >& gt; Y = [4 6 5]; >> plot(X, Y). The command plot(X, Y) cons VS .NET QR Code 2d barcode iders the vectors X and Y to be lists of the x and y coordinates of successive points on a graph and joins the points with line segments. So, in Figure 2-5, MATLAB connects (1, 4) to (2, 6) to (3, 5).

. Figure 2-5. Graphics To plot x 2 + x + 1 on the interval from 2 to 2 we rst make a list X of x values, and then type plot(X, X. 2 + X + 1). We need to use enough x values to ensure that the resulting graph drawn by connecting the dots looks smooth.

We ll use an increment of 0.1. Thus a recipe for graphing the parabola is.

>> X = -2:0.1:2; > Denso QR Bar Code for .NET > plot(X, X.

2 + X + 1). The result appears in Figur e 2-6. Note that we used a semicolon to suppress printing of the 41-element vector X. Note also that the command.

>> plot(X, f1(X)). would produce the same resu lts (f1 is de ned earlier in the section UserDe ned Functions).. 0 -2. Figure 2-6. 2: MATLAB Basics We describe more of MATLAB s graphics commands in 5. For now, we content ourselv QR for .NET es with demonstrating how to plot a pair of expressions on the same graph..

Plotting Multiple Curves Each time you execute a plo visual .net qr bidimensional barcode tting command, MATLAB erases the old plot and draws a new one. If you want to overlay two or more plots, type hold on.

This command instructs MATLAB to retain the old graphics and draw any new graphics on top of the old. It remains in effect until you type hold off. Here s an example using ezplot:.

>> >> >> >> >> ezplot( exp(-x) , [0 10]) hold on ezplot( sin(x) , [0 10]) hold off title exp(-x) and sin(x) . The result is shown in Figu QR Code for .NET re 2-3 earlier in this chapter. The commands hold on and hold off work with all graphics commands.

With plot, you can plot multiple curves directly. For example,. >> X = 0:0.1:10; > > plot(X, exp(-X), X, sin(X)). Note that the vector of x coordinates must be speci ed once for each function being plotted. 3 . Interacting with MATLAB In this chapter we describe an effective procedure for working with MATLAB, and for preparing and presenting the results of a MATLAB session. In particular we will discuss some features of the MATLAB interface and the use of script M- les, function M- les, and diary les. We also give some simple hints for debugging your M- les.

. The MATLAB Interface MATLAB 6 has a new interfac e called the MATLAB Desktop. Embedded inside it is the Command Window that we described in 2. If you are using MATLAB 5, then you will only see the Command Window.

In that case you should skip the next subsection and proceed directly to the Menu and Tool Bars subsection below..
