Hi,

I wrote an mfile that creates an mfile and executes it next... Like
this:

%Suppose that FNAME_NOEXT is a string that contains the filename of
%the data file. For example 'dat1'
%The code below creates an mfile 'dat1plotdp.m' containing all
%commands for Gnuplot.

fid = fopen([FNAME_NOEXT,'plotdp.m'],'w');

fprintf(fid,'function [] = %splotdp(DP)\n',FNAME_NOEXT);
fprintf(fid,'gset term postscript eps monochrome\n');
fprintf(fid,'gset output ''%s_DP.eps''\n',FNAME_NOEXT);
fprintf(fid,'gset autoscale\n');
fprintf(fid,'gset yrange [-1.5:1.5]\n');
fprintf(fid,'gset title ''DP''\n');
fprintf(fid,'gset xlabel ''Time (s)'' \n');  
fprintf(fid,'gset ylabel ''Error (%%)'' \n');  
fprintf(fid,'gset nokey\n');
fprintf(fid,'time = length(DP)/2;\n');
fprintf(fid,'tt = 0:0.5:time;\n');
fprintf(fid,'n = min(length(tt),length(DP));\n');
fprintf(fid,'plot(tt(1:n),DP(1:n)) \n');
fprintf(fid,'gset output\n');

fclose(fid);

%And now we execute the mfile we created....

feval([FNAME_NOEXT,'plotdp.m'],100*DP./P(1:length(DP)));

Maybe there is a more elegant method (after running you got
lots of 'plot'-mfiles) but this worked for me...

Have a nice day,
