It started out as a matrix programming language where linear algebra programming was simple. Write a function with input parameters x and n that evaluates the. Threedimensional plots in matlab % to plot z fx,y you must specify the grid x i, y j of lattice points to evalutate the function over. Plotting functions of two variables in matlab part 2 skip navigation sign in. Please note that as we decrease the increment, the graph becomes smoother.
It can be run both under interactive sessions and as a batch job. All variables inside the function are local and are not part of the matlab workspace 14 exercise 1. Matlab has since been expanded and now has builtin functions for solving problems requiring data analysis, signal processing, optimization, and several other types of scientific computations. For example, plot the value of the sine function from 0 to 2 you can label the axes and add a title. Plotting in matlab page 2 legends if you have plotted multiple dependent vectors on the same plot and want to distinguish them from each other via a legend, the. In this example, we will draw two graphs with the same function, but in second time, we will reduce the value of increment. We do this by giving the x vector and y vector and using the matlab command meshgrid. If x, y, and z are not constant, then you have three input variables and one output variable, and you would need a fourdimensional plot.
When you run the file, matlab displays the following plot let us take one more example to plot the function y x 2. It also contains functions for 2d and 3d graphics and animation. Matlab tutorial fanda yang university of minnesota 8312017. Manipulating axes subplots multiple yaxes statistics 3d. When using the histogram function to plot the estimated pdf from the. There are no facilities in matlab to do fourdimensional plots. This tutorial gives you aggressively a gentle introduction of matlab programming language. By adding a third input argument to the plot function, you can plot the same variables using a red dashed line.
