Hi all
I have 4 matrices of 4x4 size. I do
for n=1:size(P1,1)
plot3(P1(n,2),P1(n,3),P1(n,4))
hold on
plot3(P2(n,2),P2(n,3),P2(n,4))
hold on
plot3(P3(n,2),P3(n,3),P3(n,4))
hold on
plot3(Pmid(n,2),Pmid(n,3),Pmid(n,4))
hold on
savefig('3Dplot.fig')
end
but I get empty figure !!
Also , how can I parameterize the figure name, like if I have an str variable : filename and I need to save the figure as filename.fig ?
also I needed to call this code from another m file , writing the name like
plot3D
plot3D.m
'plot3D'
did not call the m file to run

Well I have scalars, but I think since they are few points I can't see them. When my matrices are so big I see the blue line of the plot clearly.
How do I use marker size then?

Or better if I could connect them with a line?
