ginput
Input data using the mouse[x,y] = ginput(n) [x,y] = ginput [x,y,button] = ginput(...)
ginput
allows you to select points from the Figure using the mouse or arrow keys for cursor positioning. The Figure must have focus before ginput
receives input.
[x,y] = ginput(n)
allows you to select n
points from the current Axes and returns the x- and y-coordinates in the column vectors x
and y
, respectively. You can press the Return key to terminate the input before entering n
points.
[x,y] = ginput
gathers an unlimited number of points until you press the Return key.
[x,y,button] = ginput(...)
returns the x-coordinates, the y-coordinates, and the button or key designation. button
is a vector of integers indicating which mouse buttons you pressed (1 for left, 2 for middle, 3 for right), or ASCII numbers indicating which keys on the keyboard you pressed.
Pick 10 two-dimensional points from the Figure window.
[x,y] = ginput(10)Position the cursor with the mouse (or the arrow keys on terminals without a mouse, such as Tektronix emulators). Enter data points by pressing a mouse button or a key on the keyboard. To terminate input before entering 10 points, press the Return key.
