MATLAB: A Quick Introduction for Scientists and Engineers (Rudra Pratap, ). 7. Built-in functions. Plotting. 3. Programming in MATLAB. M- files To start the program on a UNIX machine, just type matlab at the prompt of a command shell. You will then . The error messages that we get from MATLAB can be quite informative Rudra Pratap, Saunders College Publishing,

In addition to Windows.

That is why this book exists — to help you overcome the fear. It takes a while to understand its real power. UX Digital UNIX. All features are discussed through examples using the following conventions: The goal is to get started as simply as possible. Typing help category in MATLAB with the appropriate category name provides a list of functions and commands in that category. For almost all major topics. We believe this.

Detailed help can then be obtained for any of those commands and functions. All examples are system-independent. The texts in the white boxes inside these gray boxes are explanatory notes. Most of the examples are designed so that you can more or less follow them without reading the entire text.

We discourage a passive reading of this book.

Explanatory notes have been added within small white rectangles in the gray boxes as shown below. We encourage the use of on-line help. The best way to learn any computer software is to try it out.

After trying out the examples. These gray. For on-line help type: All commands. This subwindow lists all variables that you have generated so far and shows their type and size.

You can select a command from this window with the mouse and execute it in the command window by double clicking on it. If you can get to the command window.

You can launch any of the listed applications by double clicking on them. To begin. As software packages. You can do various things with these variables. Launch Pad: Command window: This is the main window. Command History: You also have. When you launch the application program. Current Directory: To see the options. The program includes a tutorial introduction that is worth trying.

On most systems. You can use any text editor to carry out these tasks. See Section 3. Graphics window: The commands lookfor.

After the editing is completed. It encompasses several distinct data objects — integers. Edit window: This is where you write. The following features hold for all forms of input-output: The Figure and the Editor windows appear only when invoked with the appropriate commands.

See Section 4.


No dimension statements are required for vectors or arrays. When a real number is entered as the value of a variable.

We do not discuss this facility in this book. Without it. The following facilities are provided for controlling the screen output: A semicolon at the end of a command suppresses the screen output.

The display format is set by typing format type on the command line see Fig. On most Unix systems. The default is format short. This helps in editing previous commands.

Almost all commands work the same way. On Unix machines: Type matlab on the Unix prompt and hit return. We recommend the latter. If it is not. On PCs: Welcome Aboard.

The user interface how you interact with your computer. The most convenient place. If not. To print the contents of the current active window command. To open. Use the on-line help to see how to set the path.

In the past. Not being in the right directory: Use cd or path. With path command. Simple cure is. We point them out throughout the book wherever they raise their head. There are various other little things that cause trouble from time to time. This can happen due to various reasons. Before You Start You need some information about the computer you are going to work on.

We urge you also to do the exercises given at the end of each lesson. If you are working on a computer in a public facility.

If you get stuck in the exercises. If there is a printer attached to the computer. If you are working on your own computer.

Each lesson should take about 10—15 minutes. This will take more time. In particular. But there are several correct ways of doing the problems. In public facilities. People are usually nice! Most answers consist of correct commands to do the exercises. Key features: Learn to add. Learn to plot. Plot simple graphs. Learn several ways of checking your current directory. Learn to write.

Learn to create. Create and work with arrays. Here are the lessons in a nutshell: Some commands and their output are shown below. Time Estimates: Lesson 1: The arithmetic operators are: Go ahead and reproduce the results. Here is arccosine of A semicolon at the end suppresses screen output.

More info on this later. You can also quit by selecting quit from the file menu on Macs and PCs.

The floating point output display is controlled by the format command. You can recall the value of y by simply typing y. You can also assign the value of an expression to a variable.

Here are two examples. Figure 2.

The inverse function atan2 takes 2 arguments. The same is true for hyperbolic functions. Arithmetic operations: Compute the following quantities: The argument of these functions must be in radians. Compute the following quantities. Calculate the following quantities: The inverses. This kind of context dependence. Complex numbers: The same is true for j. Exponential and logarithms: The mathematical quantities ex.


Can you check the result by hand calculation? The former case is always interpreted as a complex number whereas the latter case is taken as complex only if i has not been assigned any local value.

Creating cells We have already discussed above how to create cells using the cell function. Saving and Loading Data. Since the double integrals are performed by carrying out 1-D integrals in one direction while holding the other variable constant and then repeating the procedure in the second direction, both quad and quadl are valid choices for the method.
