1:10] To assign this range to a variable name, we use the assignment operator. We also do this to tell MATLAB what the dependent variable is and what function we want to plot. 1:10]; >> y = cos(x) Notice that we ended each line with semicolons. Remember, this suppresses MATLAB output. It’s unlikely you would want MATLAB to spit out all the x values over the interval onto the screen, so we use the semicolon to prevent this. Now we can plot the function. This is done by entering the following command: >> plot(x, y) After typing the plot command, hit the enter key.
MATLAB also allows you to create a row vector of n logarithmically spaced elements by typing logspace(a,b,n) a b This creates n regularly spaced elements between 10 and 10 . 0000 Characterizing a Vector The length command returns the number of elements that a vector contains. For example: CHAPTER 2 Vectors and Matrices 21 >> A = [2;3;3;4;5]; >> length(A) ans = 5 >> B = [1;1]; >> length(B) ans = 2 The length command can be applied to row and column vectors (see “Basic Operations with Matrices”, later in this chapter) and, as we will see below, to matrices.
01. 01:10]; >> y = cos(x); >> plot(x, y) This time we get a very nice smooth rendition of y = cos(x), this is shown in Figure 3-3. OK now we know how to get a straightforward plot on the screen. The next thing you might want to do is generate a plot that had the axes labeled. This can be done using the xlabel and ylabel functions. These functions can be used with a single argument, the label you want to use for each axis enclosed in quotes. Place the xlabel and ylabel functions separated by commas on the same line as your plot command.
