Hi all,

I am copying and pasting the code from:

http://www.mathworks.co.uk/help/symbolic/mupad_ug/create-scatter-and-list-plots.html

plot(plot::Listplot([1, 0, 1, 0, 1]))

This should give the plot shown in the website however, I get this message:

Error: File: rough.m Line: 1 Column: 11 Unexpected MATLAB operator.

It is the most basic plot, I unsure why this is giving me an error. If I could understand why that isn't working, maybe I can then work on the real issue which is to add this function into:

errorbar(ASOI,iso_Octane,STDiso_Octane,'sk-','MarkerFaceColor',[1 1 1],'MarkerSize', 5,'LineWidth', 1.3);

The real problem is that the current graph I am plotting doesn't have straight lines going through all the points (it is slightly curved). From what I understand, if I add the function 'listplot' into the line of coding above, it will connect the points with straight lines.

Jai - code from that link, and in particular that from your question title, is meant to be executed in MuPad which is part of the Symbolic Math Toolbox. Do you have this toolbox?
