MATLAB: How is Matlab GUI generated

gui generationguidematlab gui

It's just a general question I was thinking about recently.

What is the mechanism of GUI's creation used by Matlab if we use GUIDE? How is the handles structure generated? What is the order in which the individual objects are added to the figure?

I would say the best method to figure out how GUIDE works is to break points in the OpeningFcn() section of your GUIDE GUI. At this point you can peek at the handles structure and see the order inwhich things were created. As you would do for any struct the order is basically the same order inwhich you plopped it down in GUIDE. If you are looking to go away from GUIDE but use GUIDE to layout you can see my submission here

MATLAB: Roadmap – how to save the graph generated

Hi Mirella,

Thanks for your question. Please feel free to comment above in case I misunderstood something.

1) Currently, mobileRobotPRM doesn't output the underlying connectivity i.e., the nodes and the edges. If it did, one could obtain the node information (the coordinates on the map). Additionally, one could also obtain all the possible paths between a start and goal location from the output graph.

2) As you rightly pointed out, in order to generate the same set of nodes, you would have to fix the random number generator. However, please note that your maps are not identical (from what I see above). Thus, during the random nodes generation, if a node is occupied, another location will be randomly chosen in the map(this ensures that there are exactly "n=100" nodes generated in the roadmap). Even if you manage to get the same set of nodes, the underlying connectivity can also be different if the edges are not free. If an iteration counter was given instead, you could probably get around this.

I shall convey these requests to the respective team and these might be incorporated in a future release of MATLAB.

Please let me know if this answers your question.

Best,

Karsh
