is possible add sparse matrix , dense matrix using cusparse? in cublas, i'd treat matrices vectors , use axpy. cusparse have axpy sparse/dense vectors, cannot used matrices because sparse vectors , matrices have different memory structure. cusparse has dense-to-sparse , sparse-to-dense conversion routines . could: convert sparse matrix dense (e.g. cusparse<t>csr2dense ), add 2 cublas<t>geam , producing dense matrix result convert dense matrix sparse (e.g. cusparse<t>dense2csr ), use cusparse<t>csrgeam produce sparse result note using cusparse<t>geam little bit more involved single function call, usage methodology given in the documentation . also, when using cusparse<t>dense2csr , want use cusparse<t>nnz storage allocations needed.

in activity have check savedinstancestate, making sure not creating multiple fragments but question should have similar checks in fragment's oncreate() , oncreateview() because when rotate screen fragment's oncreate() , oncreateview() called everytime. question is, ok these 2 methods re-do there job after everyscreen rotation or should have savedinstancestate check well. right oncreate() makes service call , oncreateview inflates view (recyclerview) when activity or fragment recreated, oncreate() method first fired, followed onrestoreinstancestate() method, enables retrieve state savedpreviously in onsaveinstancestate() method through bundle object in argument: @ override public void onrestoreinstancestate(bundle savedinstancestate) { super.onrestoreinstancestate(savedinstancestate); //---retrieve information persisted earlier--- string id = savedinstancestate.getstring(“id”); }

can trim , replace @ same time column's name can break down in 2 parts? expected result in namel , namer name namel namer ab_1x ab 1x axg_3x axg 3x 4g_12x 4g 12x tried using query: select *, right(name, len(name)-4) namer, left(name, len(name)-4) namel mytable the problem trims this: namel ab_ axg 4g_ same namer, because i'm taking fixed size. how can eliminate "_" , achieve expected outcome? thank in advance try combination of substring , charindex functions: declare @t table(name nvarchar(10)) insert @t values ('ab_1x'), ('axg_3x'), ('4g_12x') select name, substring(name, 1, charindex('_', name) - 1) namel, substring(name, charindex('_', name) + 1, len(name)) namer @t i assume there underscore symbol in name column.

i making python module (a wrapper c library) have data files needs installed package work (coefficients magnetic field model). additionally, after installation, enviroment variable needs set folder data files ended (or else c library won't work). i think have managed install data files using manifest file , include_package_data=true (the files correctly end in directory package installed, though if there better ways i'm ears). stuck on environment variable part. how can (in setup.py) directory package installed? how can reliably set permanent environment variable in setup.py across platforms? would possible work-around set environment variable @ runtime whenever package imported? find directory can use __file__ in __init.py__ , work way there, , enviromnent variables don't have stick. however, i'm not sure c extension have access environment variable defined through python wrapper. it?

so trying write code lets me segment fuses see in picture below. have come 2 approaches: 1) based on color. threshold using opencv's inrange function. approach works fuses except brown fuse. brown fuse similar in colour fusebox , therefore it's hard segment out. 2) considered thresholding image heavily can detect white points/terminals on fuses using opencv simpleblobdetector. filter out blobs distances each other. know size of fuses, can filter out invalid fuses. approach works fuses white 1 appears in thresholded images. i hoping pointer on how segment such image. background subtraction work? my experience segmentation single approach not work difficult segmentation. if 1 algorithm works brown , other white, union of 2 should yield complete result. know nice have 1 elegant algorithm, many of best results have had resort hybrid of multiple techniques. i'd consider separating channels rgb , hue, saturation, , value , looking @ each channel separatel...

i'm programmer coming python background typically uses lexical scoping , want understand dynamic scope. i've researched on-line, still unclear me. example, i've read this page made things lot easier me, code snippets: #in dynamic scoping: const int b = 5; int foo() { int = b + 5; return a; } int bar() { int b = 2; return foo(); } int main() { foo(); // returns 10 bar(); // returns 7 return 0; } #in lexical scoping: const int b = 5; int foo() { int = b + 5; return a; } int bar() { int b = 2; return foo(); } int main() { foo(); // returns 10 bar(); // returns 10 return 0; } as understand , can see, in dynamic scoping, bar function returns 7 not 10, means foo called b variable...
