How to get access to Matlab drawings libraries

I'd like to develop a man-machine-interface with pre-defined drawings. Has Matlab got libraries of existing drawings and how can I reach them ?


drawings of what? It doesn't seem like something that would exist in Matlab, but since you didn't specify what they are drawings of, who knows?
Would they be fixed size? Bitmaps? Vector graphics? Do they need to have editable properties like "Change the angle of that arrowhead, and make the shaft a blue dashed line of width 3? Or "use these as fixed points but let me drag this point around and make the spline curve follow"?
Actually I'd like my drawings follow inputs entered. for instance, if a dialog box asks "What is the length of the line", the user can select a length (e.g. 60m) and a line is drawn with an indication that it is 60m. My issue is that I don't know what kind of drawing is available in Matlab's librairies.

Basically I'd like to use very simple drawings like lines, grids and arrows. If Matlab does not handle these drawings itself, can it call librairies of another source ?

What do you want to DO with those simple drawings? Display them, use them as an executable flowchart, use them as part of a GUI, etc.?

There are a small number of things that could vaguely be said to be "drawing library"-ish in MATLAB:
  • annotation() permits selection of line shape or drawing shape. annotation() draws on the display. Be careful, though: annotations are in figure units, not in data units
  • insertShape() from the Computer Vision toolbox permits lines and shapes to be drawn into an array (not onto the display.) There are a couple of variations of this.


Hi Walter,
Thank you for this contribution. I went to your liks and they look good. Next time I'm writting you, may I attach a simple sketch with typical shapes I'd like to draw ?
