Shpewrite error using Matlab example

EDIT: Resolved- duplicate function names, I had thought Matlab would use its own first...

When i try to use shapewrite, by following the example, i get the following error;

>> shapewrite(S, 'main_concord_roads.shp')

Error using shapewrite (line 83)

Unknown shape identification: main_concord_roads.shp

I've happily read a file in and want to ammend that before wiring it out, but its not happy? ANysuggestions?

Using R2017b.

Cheers, Tim

May be your code is partial, have you defined S before it is used? If yes, you have to share the complete code, so that people can try on it.

Try this way as example detail

shapeinfo('concord_roads');
S = shaperead('concord_roads','Selector',{@(roadclass) roadclass < 4, 'CLASS'});
shapewrite(S,'main_concord_roads.shp')

This is Mathworks documentation example.

Hi thanks for the response, alas i am following the example- as you ahve also provided, and the error remains;

>> shapeinfo('concord_roads');

S = shaperead('concord_roads','Selector',{@(roadclass) roadclass < 4, 'CLASS'});

shapewrite(S,'main_concord_roads.shp')

Error using shapewrite (line 83)

Unknown shape identification: main_concord_roads.shp

I would imagine since i can use shaperead that i have the right toolboxes. Maybe i need to install a new version of Matlab. Seems odd!
