mapping - How to read in only a subset of polygons from a shapefile in matlab -

-

i trying read in subset of polygons shapefile have. using 'shaperead' read in shapefile, can't seem pull out polygons want. know should using 'selector' pair value arguments, exampl online doesn't make sense me:

s = shaperead('concord_roads.shp','selector',...        {@(v1,v2) (v1 >= 4) && (v2 >= 200),'class','length'})

there 'station number' attribute in shapefile identifies each of polygons. want able specify polygons map (based on previous clustering analysis).

wanted_stations = [...]; % defined  [s,c] = shaperead(filename,'selector',{@(v1) any(ismember(wanted_stations,v1)) ,'station_number'}); % assuming attribute name 'station_number'

basically, each polygon, shaperead assigns value of attribute 'station_number' v1, evaluates anonymous function. values of wanted_stations vector incorporated function defined.

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
