Hey, I'm sure this is quite simple, but I am getting my self confused thinking about this!I have created a script file, which will plot a 3D line plot. I have been trying to convert the line to a "tube" shape and found some code in the file share section, where the user had created their own code that allowed you to do this. My question is, how do I call their code into my script file so that it can adjust my plot. The function file is created by: Janus H. Wesenberg and is found here; http://www.mathworks.co.uk/matlabcentral/fileexchange/5562-tubeplot

Thanks

在 MATLAB Online 中打开

Place the function m-file in the same folder of your script.

within your script, just write down the call to the function:

% your script here
...
...
% call the function
t=linspace(0,2*pi,50); % your data
tubeplot([cos(t);sin(t);0.2*(t-pi).^2],0.1);
...
% your remaining of your script follows here
...

call it when you want to plot the data. Right after the line your data is ready to be plotted. You can make a test. Write another short-easy script with some dummy data:

% dummy script/data
t=linspace(0,2*pi,50);
tubeplot([cos(t);sin(t);0.2*(t-pi).^2],0.1);
% end of dummy script

Save the previous code in a m-file next to the tubeplot m-file, in the some folder.

Run it.

It will work the same way in your original script.

You can save the tubeplot function in a file named as tubeplot.m and then use it as we normally use plot functions. I hope this is what you meant to ask.
