how to identify a row given a value in the stuct file

Hey guys, please have a look at the attached screenshot of a stuct file. Now i need for example to identify the row which has link_id 52852003, and get back the corresponding ST_NM_BASE of this row. how to write this in matlab? would be better if i can write a part of the link_id, not the whole value ( 52852 instead of 52852003 )

any help?

Typically, when looking to identify the row of a value you want to use the find() command.

[row, col, val] = find(data_map.link_id==52852003);

This probably won't work perfectly, but it should be a place to start.

it does not work, Error using == Too many input arguments.

Try [data_map.link_id], rather than the unbracketed version I sent before.
