Hello This is a record from my experience about ginput.
If you have installed the octave-forge plot package, the function ginput does not work because the plot package also has ginput.m and made conflict with ginput octave itself. Please rename .....\Octave\3.2.4_gcc-4.4.0\share\octave\packages\plot-1.0.7\ginput.m like ginput.xx.m. For old PC, response of ginput might be slow. (might take several seconds to respond). This is due to the pipe handling on windows being not optimized. To overcome the slowness, the same technique to improve plot speed proposed by Olli Saarela can be used. Please refer http://n4.nabble.com/Plotting-with-3-2-0-on-Windows-is-SLOOOOOOWWWW-td1637250.html#a1637250 For ginput case, please add sleep(0.05); at ...\Octave\3.2.4_gcc-4.4.0\share\octave\3.2.4\m\plot\__gnuplot_ginput__.m in line 112.
