# matlab plot with range

x -1:.1:1 Define the range of x y x.3 Raise each element in x to the third power Now that you have generated some data, you can plot it using the MATLAB plotting tools. To start the plotting tools, type plottools MATLAB displays a figure with plotting tools attached. Here are two functions plot once with EZPLOT and once with PLOT. Ezplot vs plot in Matlab.You need to indicate the range of variation of the main variable, and you need to express the first variable with respect to the second. Example 2. sets the horizontal range to [1, 1], but lets MATLAB choose the vertical limits based on the data that is plotted. Some other commonly used commands to control the axis behavior are followThe result is shown in Figure 13.11. Combining multiple plots with a. 3. You can also specify a range of numbers in a defined vector or matrix using the colon operator. The colon causes MATLAB to step in sequence through theplot(x1,y1,line-type1,x2,y2,line-type2). You can also create plots with either or both axes changed to log-scale. All of these functions follow the As you can see in Figure 3.13 it is difficult to see the y1 values since MATLABs auto-scaling is choosing the y-axis limits so as to display all the data points.

Figure 3.13 Using plot to graph data sets with a large range of y-axis values is not always acceptable. Instead we could use plotyy to plot the MATLAB plots the vector on the x-axis and the value of the sine function on the y-axis. t 0:pi/100:2pi y sin(t) plot(t,y). MATLAB automatically selects appropriate axis ranges and tick mark loca-tions plot(Y) creates a 2-D line plot of the data in Y versus the index of each value. If Y is a vector, then the x-axis scale ranges from 1 to length(Y).Create a 2-D line plot of Y. MATLAB plots each matrix column as a separate line. By default, MATLAB finds the maxima and minima of the data and chooses the axis limits to span this range.Multiple Data Sets in One Graph. Multiple xy pair arguments create multiple graphs with a single call to plot. MATLAB. range where we sample generate sample points render the plot. By default, MATLAB draws a smooth curve through those sample points.
