I need to optimise code that counts pos/neg values and remove non-qualified values by time. I have queue of values with time-stamp attached.
What is the fastest way to lookup the index of a value in sorted vector in MATLAB? That is, is there a fast find(vector == myNumber, 1, \'first\') for whe开发者_如何学Gon vector is sorted?
I have been working on SSE optimization for a video processing algorithm recently. I need to write the exactly same algorithm in C code to cross-check correctness of the algorithm. I forgot about this
I am trying to generate a PDF file based on a dynamically generated HTML report that our webapplication has generated.
I have a mySQl innodb database which has a couple of tables which store different kind of transactions of a user. In order to show a custom \'Account Statement\', I have to fetch data from all of thes
I\'m working on a student project team building application. I\'m familiar with optimization but haven\'t used Microsoft Solver Foundation before. I have my constraints worked out but am having troubl
This is the problem I\'m solving (it\'s a sample problem, not a real problem): Given N numbers , [N<=10^5] we need to count the total pairs of
The following three pieces of code achieves exactly the same effect. Yet, when compiled with -O3 on GCC 4.5.2 the times for a lot of iterations vary quite markedly.
I have an array of 300K strings which represent dates: date_array = [ \"2007-03-25 14:24:29\", \"2007-03-25 14:27:00\",
The following piece of code achives the desired results, but performance is extremely slow: SearchResultCollection absaUsers = ABSAds.FindAll();
