Plot graph using line command
显示 更早的评论
Hi all,
I would like to know what returns the command line. For example, I have this line.
h = line([x],[y],'color','r');
Where x and y are arrays of double values. These are the values:
x =
0.3211 0.3906 0.4581 0.5233 0.5860 0.6461 0.7033 0.7576
y =
0.4400 0.5400 0.6400 0.7400 0.8400 0.9400 1.0400 1.1400
I want to plot "h" but it shows nothing.
Somebody can tell me how to generate and use "h" as a line. For example, I want to use this "h" to do intersections with other lines.
Thanks a lot.
Raúl.

The return value from line() is the handle graphics "handle" that represents the drawn line segment and its properties. The drawn line would already be present in your figure.
line() is not a data structure for representing lines for general manipulations such as finding intersections with other lines. line() is a graphics call.

I cannot think of many at the moment, but what kind of manipulations were you thinking of?

You opened a new Question about that; I answered there.
