Calling and Using function file to adjust plots

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

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
...

Thanks for the quick response :) Where exactly would I call the function file in my script? Would it be right in the end? or, Just before, or, just after, where I have the plot command? Also I'm confusing my self with how to call a function file in a script file.

[David Sanchez]

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.

Perfect! Got it working :D

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.

[Mazhar]

I have saved the function file as tubeplot.m. Now, in my script I should change the 'plot3(.....)' to 'tubeplot([....]..)'.

[David Sanchez]

right, but watch out for the input parameters. Make sure your are sending the right data.

yup! I guess you got it!
