Jan 9, 2019 · Create a function of two variables. Simplest is to learn about function handles. Don't forget to use the correct operators, that will allow vectorized operations between arrays of x1 and x2. Here that means you need to use the .^ and .* operators.

fplot(f) plots the curve defined by the function y = f(x) over the default interval [-5 5] for x. fplot(f,xinterval) plots over the specified interval. Specify the interval as a two-element vector of the form [xmin xmax]. = funy(t) over the default interval [-5 5] for t. fplot(funx,funy,tinterval) plots over the specified interval.

Jun 19, 2021 · So data can be seen as variables x,y,z,a,b,c,d...etc, sorted in columns. The idea is to choose a condition (for example, when x=1) and plot the correspondant data from two other variables. Here's an example of my code, that works on a txt file of 4 columns: plot (xl,Errvector,'linestyle','none','marker','.')

Dec 16, 2013 · I have a problem to plot a function with 2 variables: if i do: x= linspace (0,5); y=linspace (0,5); [x,y]=meshgrid (x,y); z=log (x.*sqrt (y-x)); mesh (x,y,z); I get this error: Error using mesh (line ...

Sep 19, 2014 · Does anyone have an example of how to plot a 2-variable function with integration in MatLab (without using MuPAD)? Here is what I've got:

Jun 1, 2013 · Plotting a function of two variables would normally mean a 3-dimensional plot - in MATLAB you would use the function plot3 for that. To plot your function f(x,y) in the interval [-10,10] for both X and Y, you could use the following commands: x = [-10:.1:10]; y = [-10:.1:10]; plot3(x, y, x.^2 + 3*y) grid on

Oct 6, 2023 · Learn how to plot a function of two variables in MATLAB with step-by-step instructions and examples. Explore the process of plotting functions of two variables in MATLAB with comprehensive instructions.

Dec 14, 2022 · Below is the process to plot two variables function in Matlab: Algorithm: Define a grid of (x,y) points. Apply the function to the grid to get values of z. Use meshgrid() function. Plot the resulting mesh. Let’s take an example to plot a two-variable function. Below is the plotting of the z= x^3 + y^3 function which is a two-variable function.

Dec 27, 2023 · MATLAB provides powerful visualization capabilities to plot functions with two variables in 3D space. This allows uncovering dependencies and trends impossible to observe in raw tabular data. In this comprehensive guide, we will explore the essential methods for visualizing functions of two variables using MATLAB:

Feb 12, 2019 · I'm trying to plot a function that takes 2 independent variables of different ranges. The 2 variables are theta and phi, as follows: -pi < theta < pi. 0 < phi < pi. The function that I'm trying to plot is: | sin (2 * pi * sin (theta) * sin (phi)) / sin ( (pi / 2) * sin (theta) * sin (phi)) |^2.
