    [SOLVED] Re: plot problems

    Your function definition has unbalanced parentheses, it is missing a right bracket. It probably needs the extra one on the end, but be careful to make sure you put it in the correct place. Also you...

    Re: How to plot 3D surfaces from f(x,y) data

    Re: How to plot 3D surfaces from f(x,y) data

    You can do this with gnuplot.

    set dgrid3d
    splot "yourdatafile" using 1:2:3 with lines
    This grids the data for plotting. You can use the help command in gnuplot, eg.:
    help dgrid3dto find out...

    Re: Omnetpp

    Have you opened up a new terminal and tried this? You need to source the .bashrc file

    source ~/.bashrc
