You can export figures in many different formats from the File> Save As menu – and you can also print your plot directly. After the running MATLAB program, you will get a number of graphs on the single MATLAB display. You can change axis label fonts, the line thickness and color, the background, and so on – usually by double-clicking what you want to change and then using the pop-up editor. You are plotting graphs for multiple mathematical equations like a sin wave, cos wave, exponential function on the same MATLAB display. A menu should open up that will allow you to add x and yĪxis labels, change the range of the x-y axes add a title to the You see the first plot added to the display. Type p1 plot (x, sin (x), ‘g-’) and press Enter. It tells MATLAB to place the first plot in the first space in the grid.

Submit plots for parts (a) and (b) above and the M-code that produced them. Find and replace all complex entries with NaN's, then replot the function ysqrt(9-x2). Use writng to explain any mysterious horizontal segments in your plot. Plotting with MATLAB MATLAB is very useful for making scientific and engineering plots. For example, you can go to Tools> Edit Plot, then double-click the plot. This function creates a grid consisting of one row and three columns. Use Matlab's plot command (with no adjustments) to draw the graph of ysqrt(9-x2) on the interval -4,4.

You can also increase the number of independent variable according to you equation.Matlab lets you edit and annotate a graph directly from the window. The ezplot() function automatically assigns values to the independent variables. In the above code, we declared the equation as a function f, and as you can see the output is the same as the above output with only deference in independent variable values. For example, let’s plot an equation that has one dependent variable and one independent variable. Finally, you can plot the equation using the ezplot() function. To plot the equation using ezplot(), first, you need to define your equation as a function using the function and after that, you need to pass the independent variables inside the function. Plot an Equation Using ezplot() Function in MATLABĬonsider you want to plot an equation in MATLAB which have one dependent variable and one or more independent variables.

MATLAB code for Exponential function: Here is code the function y(x) in MATLAB. Solution: In this problem, this equation has trigonometric and exponential functions.

You can also increase the number of independent variable according to you equation. Problem 3: How to plot the Exponential Function in MATLAB Let’s take an example of a trigonometric and exponential function. So you will basically type in the name of the function first and then type in the interval. The proper syntax for fplot is: fplot (name of function, interval). To plot an anonymous function, you must use fplot even if your function is not named 'f'. In the above code, we declared a random value of the independent variable to calculate the values of the dependent variable, you can change the values of the independent variable according to your requirements. On the next line you will write a statement to plot the function. To plot the equation, you need to declare the independent variables present in the equation and then you can find the value of the dependent variable, and using these values you can plot the equation using the plot() function. Plot an Equation Using plot() Function in MATLABĬonsider you want to plot an equation in MATLAB which have one dependent variable and one or more independent variables. It is often very easy to 'see' a trend in data when plotted, and very difficult when just looking at the raw numbers. In this tutorial, we will discuss how to plot an equation by declaring the value of the independent variables present in the equation and then using the plot() function to plot it and how to plot the equation using ezplot() in MATLAB. The plot function in Matlab is used to create a graphical representation of some data. Plot an Equation Using ezplot() Function in MATLAB.Plot an Equation Using plot() Function in MATLAB.
