I am not sure what mathworks decided to change this time. In any case, please feel free to fork the project on github, make the fixes, and send a pull request.

@kavita: Have you downloaded the dependencies.tar, extracted and added it to your matlab path ? It can be found here: https://github.com/johnyf/openstreetmap/releases

In there you will find the renamed xml2struct_fex28518 function. The rename is to avoid name conflicts with the bioinformatics toolbox (removing that from your installation is not recommended).

The original error that you see did not relate to the bioinformatics toolbox, since it couldn't find xml2struct_fex28518, not xml2struct.

The persistency of xml2struct in matlab's path may be due to caching (e.g., compare `which` with `hash` in a bash shell). Perhaps after restarting matlab it won't find xml2struct any more. In any case, it is not the cause for the error.

Just select "Export" at the top left and zoom in enough so that it won't complain on the export pane (opens on the left after you click "Export") that the area is too large to be exported. Then hit the blue "Export" button on the left pane, and that will download the ".osm" file that contains the XML data you need.

Material opacity is supported by IDTF. You can try experimenting with changing the alpha value from 1.0 to less than 1.0, i.e., undoing this change:

Delighted with this. However, not yet working with the Updated Graphics System on the 2014b Prerelease (can't see why). Is anyone else interested in trying this on the Prerelease?

Undefined function 'isnan' for input arguments of type
'matlab.graphics.GraphicsPlaceholder'.

Error in u3d_pre_quivergroup (line 63)
sh(isnan(sh) ) = [];

Error in fig2u3d (line 198)
[quiver_vertices, quiver_edges, quiver_colors] = u3d_pre_quivergroup(ax);

dear all

i started with usage_example but the follwoing error comes

>> usage_example
Undefined function 'xml2struct_fex28518' for input arguments
of type 'char'.

Error in load_osm_xml (line 27)
map_osm = xml2struct_fex28518(filename); % downloaded osm
file

Error in parse_openstreetmap (line 36)
map_osm = load_osm_xml(openstreetmap_filename);

Error in usage_example (line 28)
[parsed_osm, osm_xml] =
parse_openstreetmap(openstreetmap_filename);

then i read the various comments from this page, then i tried the following

1)i extracted the smaller map file from www.openstreetmap.org , even the error is same.

2) the i typed the command
>> which xml2struct
C:\Program Files\MATLAB\R2013a\toolbox\bioinfo\biodemos\xml2struct.m

as a solution i removed the bioinfo folder from the follwing path
C:\Program Files\MATLAB\R2013a\toolbox\

even then the same error appears and when i am typing the command ">> which xml2struct
" again it shows the same result. how to resolve this error.kindly suggest and help me plz.
