Specific features are extracted to construct the input vector X. We then train a classifier to predict whether a pair of inherent structures forms a double well potential (DW) or not. The DW is finally processed using a multi-layer stacking strategy to predict the quantum splitting of the ...
I started using nlohmann::json today (thanks for it) and I wanted to check whether a certain value is contained in an array: I used find(). It compiled but it does not work. #include <json.hpp> using json = nlohmann::json; int main(void)...
Examining the value ofszmade it clear enough:MscIsFloatOrVectorConstantreturns the size of the constantif it is found, and 0 otherwise. In this buggy case, it returns 0, and we underflow the array field in the function-local structvval. The fix is equally straightforward: following idioms ...
A = [1 2; 3 4]; B = [2 1; 4 3]; Which will yield a vector, E = [0; 0]; Also this is also requires that each row has exactly one common value. 댓글을 달려면 로그인하십시오. 이 질문에 답변하려면 로그인하십시오. ...

It is possible to search for sequences of identical values by simply iterating over a vector, but this is very slow in R. A much faster way to find sequences is to use the rle() function.# Example data v<-c("A","A","A"
