I can't make it to work with the carriage return but it does work great with the space button (32) and mouse left button (1), use the carriage return or other button to stop entering points.
button=1;xx=[];yy=[];
while ((button==1) | (button=32))
[x,y,button]=ginput(1);
plot(x,y,'rx') %mark the point
if ((button==1) | (button=32))
xx=[xx x];yy=[yy y];
end
end
This code results on vectors 1xN where N is the number of points marked.
If you want to combine them in just one array do
XYP=[xx' yy'];
or
XYP=[xx;yy];
If you want in cell format use the function mat2cell
You ask for cell and array in the same question?!
