Here we discuss Where can MATLAB be used along with the Syntax and outputs.Let's look at the anatomy of a format string followed by some short example programs to show the different settings in action. In addition to its computing powers, MATLAB also provides its users the ability to draw and visualize the data for better understanding and drawing inferences.Īll this is done in a significantly less amount of time when compared to writing a program in a scalar and non-interactive language such as C. This allows us to solve computing problems, especially the problems with matrix & vector formulations. MATLAB is a system whose basic data element is an array that does not require any dimensioning. To get the desired color of the markers, we can use fp.MarkerEdgeColor = ‘b’ Īfter implementing the above functions, our final output will be:.To get marker points on the plot, we can use fp.Marker = ‘x’.To change the color of the line, we can use fp.Color = ‘r’.To change the line of the plot into a line with colons, we can use fp.LineStyle = ‘:’.Let us now understand various ways in which we can modify properties of our plot obtained from fp: Let us first draw plot for a sin wave using the function fp = fplot sin(x)) So, we can change the properties of a plot that is already created, by using this function.

This function is used to modify the properties of an existing plot. For example, if we pass ‘Linewidth’, 3 as an argument in any of the above examples, we will get a plot of width 3. This function is used to define properties of the line in the plot as per the pair of name-value passed in the argument. Similarly, we can use ‘b’ for blue color and ‘y’ for yellow color. The output that we will get here will be a red color plot of square function: i.e user can decide how he/she wants to visualize the final output.įor example, if we need to plot a graph of red color, we will pass ‘r’ as the argument in any of the functions explained above. This function is used to get the marker symbol, line style or color of the plotline as per the choice of user.

The output of the final function fplot (at, bt), will be Here we define 2 functions ‘at’ and ‘bt’ as follows: This function will plot the 2 functions passed as arguments. The output of our example will be as shown below: For this example, we will take the interval 0 to 3. Here we have taken the same function as in the example above. Let’s understand this clearly with the help of an example: We need to specify the interval as a 2-element vector in the form In the above example, the interval was defaulting, however, if we need the interval of our choice, we can use fplot (f, xinterval).

Here we have taken square function as the one which we need to plot. Let’s understand this function with the help of an example: The plot is created over the default interval. This will plot the graph defined by the function y = f(x). Let us now understand all the above-mentioned functions one by one: 1. It is straightforward and easy to visualize a trend in data when it is plotted as compared to just looking at the raw figures. We use a plot function to create a graphical representation of our data. As the name suggests, the purpose of the plot function is to plot the graph of a function in MATLAB. The objective of this article is to have a thorough understanding of plot functions in MATLAB.

MATLAB comprises a number of techniques to perform the above-mentioned uses. Hadoop, Data Science, Statistics & others
