MATLAB Programming 48 - plot a graph

To plot the graph of a function, you need to take the following steps:

Define x, by specifying the range of values for the variable x, for which the function is to be plotted

Define the function, y = f(x)

Call the plot command, as plot(x, y)

Following example would demonstrate the concept.

Let us plot the simple function y = x for the range of values for x from 0 to 100, with an increment of 5.

Create a script file and type the following code:

x = [0:5:100];
y = x;
plot(x, y)

When you run the file, MATLAB displays the following plot:
