【Help】Error using contour (line 81), Not enough input arguments.

Hello! I have trouble in using contour function to plot, it always returns "Error using contour (line 81), Not enough input arguments."

I am using Matlab2014a, it returns "Error using contour (line 81), Not enough input arguments." when I use Run (F5), and it goes through but displys no picture when I use （ctrl+shift+enter）.

Hoping for help, Thanks!!

The program is as follows,

    x=Data(1,:);
    y=Data(2,:);
    f=Data(5,:);
    xx=reshape(x,301,43);
    yy=reshape(y,301,43);
    ff=reshape(f,301,43);
    v=[0,0];

    figure1 = figure('PaperSize',[20.98404194812 29.67743169791]);
    axes1 = axes('Parent',figure1,...
        'PlotBoxAspectRatio',[1 2.27272727272727 90.9090909090909],...
        'Layer','top',...
        'XMinorTick','on',...
        'YTick',[0 0.1 0.2],...
        'YMinorTick','on',...
        'TickDir','out',...
        'FontSize',20,...
        'FontName','Times New Roman',...
        'DataAspectRatio',[1 1 1]);
    axis(axes1,[-0.021,0.021,0,0.2]);
    xlabel(axes1,'{\it{x}}/m','FontSize',25,'FontName','Times New Roman');
    ylabel(axes1,'{\it{y}}/m','FontSize',25,'FontName','Times New Roman');
    axis equal;

    set(gcf,'color',[1 1 1],'Position',[0,0,232,680]);
    set(gca,'position',[0.15 0.11 0.95 0.86]);

    box(axes1,'on');
    hold(axes1,'all');

    [C,hh]=contour(xx,yy,ff,v,'r','LineWidth',2);

What is the file name that you stored this code in?

[Ren Zetian]

Thanks! I changed the original file name "contour-plot.m" and it works well now!

[Walter Roberson]

Do not use dashes in the name of .m files. The first character must be a letter A through Z or a through z, and the characters after that must be letters or the digits 0 through 9, or the underscore character.

Converting my comment into an answer so it can be marked as solved:

The difficulty was that the file the user had stored in was itself named contour.m which was conflicting with the contour routine.
