Thank you. That solved my plotting problem!

However, when I use the command "[x,y,b]=ginput(2)" I get the warning "warning: implicit conversion from real matrix to real scalar" 6 times, and after klicking several times in the graph window, I do net get my command prompt (>) in the Octave window back, until I hit Ctrl-C.

I think this is the infamous "oct2mat package problem", and not really a bug in Octave.  Please try executing the command

  pkg rebuild -noauto oct2mat

at the octave prompt and then restart Octave.  More info about this problem may be found here:

I have installed Octave 3.2.4 under Windows 7 Home Premium 64bit. The "plot" command does not work properly. When typing

t=0:0.1:10; s=sin(t); plot(t,s);

for the first time I get an error report: "warning: isstr is obsolete and will be removed from a future version of Octave, please use ischar instead".
Upon trying a second time by just repeating the line above, I do get a new window with a correct plot in it, but this figure window immediately freezes (i.e. when I move the cursor over this window, it always assumes the "busy cursor" form), until I give a "clf" or "cla" command on the octave command line. The graph is then erased, but the window unfreezes, so that I can close it.
