why do i have matlab a and matlab b on my computer?

For instance, let's say you have the following polynomial: Polynomial into the vector in descending order. To create a polynomial in MATLAB, simply enter each coefficient of the In MATLAB, a polynomial is represented by a vector. You may visit the plotting page to learn more.

Basic plotting is very easy in MATLAB, and the plot command has extensive add-on capabilities. The plot contains approximately one period of a sine wave. Title( 'Sine Wave as a Function of Time') The commands after the plot function ( title, xlabel, ylabel) will add annotations to the plot. Vector (the semicolon after each statement tells MATLAB we don't want to see all the values) and then compute the sin valueĪt each time. Suppose you wanted to plot a sine wave as a function of time. It is also easy to create plots in MATLAB. MATLAB even allows you to write your own functions with the function command follow the link to learn how to write your own functions and see a listing of the functions we created for this To determine the usage of any function, type help at the MATLAB command window. Commonly used constants such as pi, and i or j for the square root of -1, are also incorporated into MATLAB.

MATLAB contains all of the standard functions such as sin, cos, log, exp, sqrt, as well as many others. Each function is a block of code that accomplishes a specific

To make life easier, MATLAB includes many standard functions. Subtraction of vectors of the same length works exactly the same way. If the two vectors are the same length, it is easy. Now suppose, you would like to add two vectors together. First, suppose you would like to add 2 to each of the elements in Manipulating vectors is almost as easy as creating them. Let's say you want to create a vector with elements between 0 and 20 evenly spaced in increments of two (this method is frequently For example, to create the vector a, enter the following into the MATLAB command window (you can Copy and Paste from your browser into MATLAB to make it easy) and MATLAB should return the following: Enter each element of the vector (separated by a space) betweenīrackets, and set it equal to a variable. Let's start off by creating something simple, like a vector.

You shouldīe able to re-do all of the plots and calculations in the tutorials by cutting and pasting text from the tutorials into the The idea behind these tutorials is that you can view them in one window while running MATLAB in another window. On MATLAB, please visit the MathWorks home. Macintosh, and Windows environments a student version of MATLAB is available for personal computers. There are many different toolboxes available which extend the basic functions of MATLAB into differentĪpplication areas in these tutorials, we will make extensive use of the Control Systems Toolbox. MATLAB is an interactive program for numerical computation and data visualization it is used extensively by control engineersįor analysis and design.
