You can try all these codes with different functions as well. In this tutorial, I explained the step-by-step process and examples in MATLAB to plot a function of two variables. In MATLAB, we can plot a function of two variables using different types of plots. Title('Two Variable Function Contour Plot') % Plot the function using the contour plot % MATLAB code to plot a function of two-variable using contour plot The following example shows the MATLAB code implementation to plot a function of two variables using the contour plot. For this, we use the "contour" function in MATLAB. In MATLAB, we can plot a function of two variables using the contour plot. Output Plot a Function of Two Variables Using Contour Plot Title('Two Variable Function Scatter Plot') % Plot the function using the scatter plot % MATLAB code to plot a function of two-variable using scatter plot Here is an example demonstrating how to plot a function of two variables using the scatter plot. For this, we have a built-in function "scatter" in MATLAB. We can also plot a function of two variable using the scatter plot. Output Plot a Function of Two Variables Using Scatter Plot Use h to set properties of the scatter object after creation. h paretoplot ( ), for any previous input syntax, returns a handle h to the resulting scatter object. Use this syntax is your objective functions are not labeled. Title('Two Variable Function Surface Plot') paretoplot (val,objindex) creates a Pareto plot of the objectives listed in objindex. % Plot the function using the 3D surface plot % MATLAB code to plot a function of two-variable using surface plot Let us see an example to understand how to use the "surf" function to plot a function of two variables in MATLAB. For this, there is a built-in function in MATLAB library named, "surf" that plots a 3D surface plot for the defined function. In MATLAB, we can also plot a function of two-variables using the surface plot. Output Plot a Function of Two Variables Using Surface Plot Title('Two Variable Function Mesh Plot') % Plot the function using the mesh surface plot % MATLAB code to plot function of two-variable using mesh surface plot The following example demonstrates how we can use the "mesh" function to plot a function of two-variables. We can use it to plot a function of two-variables. In MATLAB, we have a function "mesh" that is used to plot a 3D surface plot of a function. Plot a Function of Two Variables Using Mesh Plot Let us understand the above given algorithm with the help of MATLAB examples. Hence, plotting a function of two variables in MATLAB is a simple four step process. Step (4) − Create a plot of the function. Step (3) − Define a function in two variables that you need to plot. For this, use the "meshgrid" function in MATLAB. Step (2) − Create a grid of x and y points. Step (1) − Define the range of x and y points. The step-by-step process to plot a function of two variables in MATLAB is explained below. Plot a Function of Two Variables in MATLAB In this tutorial, I am going to explain the process of plotting a function of two variables in MATLAB. MATLAB provides various built-in functions to plot a function of two variables with the help of different types of plots like mesh, surface, scatter plots, etc.
