Solved: The following little program assigns column names to a row vector mu_vec. However, if this processing is carried out within a function, then
When your function returns the std::string is destroyed. That certainly qualifies as modification.You need to store the memory for your string somewhere that is stable until the C# code is done or has made a copy of a string. (In general you don't want to return pointers from a C++ ...

We describe an affordable and easy to use vector able to safely transport scientific data and samples from the stratosphere to the ground, a desirable tool for several scientific measurements. Such a system was originally thought for physically recovering data media from the Olimpo [1] experiment,...
> x = c(NA) > min(x) [1] NA > max(x) [1] NA In this example, we set the value of the vector that we put through the maxx and minxfunctions to a missingvalue. The result is amissing value but no error. > plotting = function(y,x,table){ ...
This function takes the mean value, aka the average, of the values in a vector or data frame column used in the function. > a = c(1,2,3,4,5) > b = c(TRUE,FALSE,TRUE,TRUE,FALSE) > c = c(“a”,”b”,”c”,”d”,”e”) ...
When querying a vector table which contains Albuquerque Police Area Commands as polygons, the following code will extract a single area command as a raster: cursor.execute("SELECT ST_AsPNG(ST_asRaster(geom,150,250,'8BUI')) from areacommand where name like 'FOOTHILLS';")c=cursor.fetchall(...
I have a Data class which holds pointers to Element owned by only Data. I want to return these elemens in a container (list or tuple) [1]. When returning the internal vector<Element*> container of Data by reference everything works, but ...
