Find row Index of strings in cell Array (Matlab) -


if have cell array c:

c =  {'name'  'hh' '23' []     []     'last'  'bb' '12' '8'    'hello'     'in'    'kk' '12' '2131' []     'name'  'kk' '23' []     []     'name'  'cv' '22' []     []     'name'  'ph' '23' []     [] } ;

how can row index of rows have 'name' in first column , '23' in third column?

indexresult = [1,4,6]

the simplest way this (all-versions compatible) use strcmp, can accept cell arrays , "string compare".

one liner

indexresult = find(strcmp(c(:,1), 'name') & strcmp(c(:,3), '23')); % indexresult = [1; 4; 6];

explanation

% logical array of rows first column 'name' logicalname = strcmp(c(:,1), 'name'); % logical array of rows third column '23' logical23 = strcmp(c(:,3), '23'); % logical array both of above true, using , (&) logicalname23 = strcmp(c(:,1), 'name') & strcmp(c(:,3), '23'); % indices logical array using find indexresult = find(strcmp(c(:,1), 'name') & strcmp(c(:,3), '23')); % if wanted row vector instead of column vector, transpose indexresult = find(strcmp(c(:,1), 'name') & strcmp(c(:,3), '23')).';

if want case insensitive (matching 'name', 'name', 'name', ...) use strcmpi instead of strcmp.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...

Add new key value to json node in java -

i have json file : { "id":1, "name":"abc", "addressdetails": { "city":"newyork" } } i wanted add 1 more key-value ("pincode" : "414141") node 'addressdetails'. i tried using : objectmapper mapper = new objectmapper(); jsonnode root = mapper.readtree(new file("d://test.json")); objectnode node = mapper.createobjectnode(); node.with("addressdetails").put("pincode", "414141"); but it's not getting added, there way can ? you can try you should modify file path objectmapper mapper = new objectmapper(); objectnode nodes = mapper.readvalue(new file("d:\\test.txt"), objectnode.class); nodes.with("addressdetails").put("pincode", "414141"); mapper.writer().writevalue(new file("d:\\test.txt"), nodes);
