Hi,
I have matrix
00001
00000
00000
01000
How I can visualize this, assuming that values "1" are points, that have to be connected by a line? I'd like to end up with such plot:
So coordinates of connected points are positions of elements in matrix that have value=1
Thanks

Which kind of visualization?

I've updated the question. Just simple line that connects two points.

You don't seem to be using the same coordinate system for each point. you seems to be using 0-based coordinates for the lower-left point, which is why it lies at (0,1). However, the 0-based coordinate of the upper-right point should then be at (4,3) not (5,4).

Matt J, Yes, was just in a hurry while plotting an example. Azzi Abdelmalek, yes

[I,J]=find(yourMatrix);
plot(J-1,size(yourMatrix,1)-I) %in 0-based coordinates

It should start at 2, i suppose.
If you're saying you now want 1--based coordinates, just change the above to
plot(J,size(yourMatrix,1)-I+1)

hi,
try simply :
f=[ 00001
00000
00000
01000];
plot(f);
You will get the same plot as your figure, except the slope starts at 3.
But in your question, one can think that you want to visualize MxN array ,

that doesn't plot what I want to see. It should start at 2, i suppose.
