julia find in matrix with (row,col) instead of index - in julia can find coordinates of elements in matrix via: julia> find( x -> x == 2, [ 1 2 3; 2 3 4; 1 0 2] ) 3-element array{int64,1}: 2 4 9 these values right prefer (row,col) tuples instead. (1,2) (2,1) (3,3) what easiest way accomplish in julia? i don't believe there inbuilt way it, here function it function findmat(f, a::abstractmatrix) m,n = size(a) out = (int,int)[] in 1:m, j in 1:n f(a[i,j]) && push!(out,(i,j)) end out end e.g. julia> findmat(x->x==2, [ 1 2 3; 2 3 4; 1 0 2] ) 3-element array{(int64,int64),1}: (1,2) (2,1) (3,3) if big number of items satisfy status might more efficient in 2 passes, uncertainty it. matrix find julia-lang

pass vectors by pointer and reference in c++ - a quick question how safely pass , utilize vectors in c++. i know when using vectors have careful addresses them , elements because when dynamically alter size may alter address (unless utilize reserve etc. i'm imagining not know how much space need). now want pass existing vector (created elsewhere) function adapts , changes size etc. i'm little unclear safe because accomplish of pointers. on top of there using references vector , muddies water me. for instance take 2 next functions , comments in them void function1(std::vector<int>* vec){ std::cout<<"the size of vector is: "<<vec->size()<<std::endl; //presumably valid here (int i=0;i<10;i++){ (*vec).pushback(i); //is safe? or fail? // or: vec->pushback(i); difference? } std::cout<<"the size of vector is: "<<vec->size()<<std::endl; //is line valid he...

python - What exactly does Spyder do to Unicode strings? - running python in standard gnu terminal emulator on ubuntu 14.04, expected behavior when typing interactively: >>> len('tiθ') 4 >>> len(u'tiθ') 3 the same thing happens when running explicitly utf8-encoded script in spyder: # -*- coding: utf-8 -*- print(len('tiθ')) print(len(u'tiθ')) ...gives next output, regardless of whether run in new dedicated interpreter, or run in spyder-default interpreter (shown here): >>> runfile('/home/dan/desktop/mwe.py', wdir=r'/home/dan/desktop') 4 3 but when typing interactively in python console within spyder: >>> len('tiθ') 4 >>> len(u'tiθ') 4 this issue has been brought elsewhere, question regards differences between windows , linux. here, i'm getting different results in different consoles on same system, , python startup message in terminal emulator , ...

python - Pandas - consecutive values must be different - i want subsample rows of dataframe such pairs of consecutive values in given column different, if 2 of them same, keep, say, first one. here example p = [1,1,2,1,3,3,2,4,3] t = range(len(p)) df = pd.dataframe({'t':t, 'p':p}) df p t 0 1 0 1 1 1 2 2 2 3 1 3 4 3 4 5 3 5 6 2 6 7 4 7 8 3 8 desireddf p t 0 1 0 2 2 2 3 1 3 4 3 4 6 2 6 7 4 7 8 3 8 in desireddf, 2 consecutive values in p column different. how this? >>> df[df.p != df.p.shift()] p t 0 1 0 2 2 2 3 1 3 4 3 4 6 2 6 7 4 7 8 3 8 explanation: df.p.shift() shifts entries of column p downwards row. df.p != df.p.shift() checks each entry of df.p different previous entry, returning boolean value. this method works on columns number of consecutive entries: e.g. if there run of 3 identical values, first value in run returned. python pandas dataframes distinct-...
