How can I create a const boost matrix?
The following did not work:
const boost::numeric::ublas::matrix<double> arrayM(1, 3) = { {1.0, 2.0, 3.0} };

I am trying to use Boost::Fusion (Boost v1.42.0) in a personal project. I get an interesting error with this code:
#include "boost/fusion/include/sequence.hpp"
#include "boost/fusion/include/make_vector.hpp"
#include "boost/fusion/include/insert.hpp"
#include "boost/fusion/include/invoke_procedure…

I'm trying to lay out vertices using the Boost Graph Library. However, I'm running into some compilation issues which I'm unsure about. Am I using the BGL in an improper manner? My code is:
PositionVec position_vec(2);
PositionMap position(position_vec.begin(), get(vertex_index, g));
int iterations…

Hello, I want to save boost signals objects in the map (association: signal name ? signal object). The signals signature is different, so the second type of map should be boost::any.
map<string, any> mSignalAssociation;
The question is how to store objects without defining type of new signal…

I have a code that has been working for almost 4 years (since boost 1.33) and today I went from boost 1.36 to boost 1.42 and now I have a problem.
I'm calling a custom formatter on a string to format parts of the string that match a REGEX.
For instance, a string like: "abc;def:" will be changed…

I'm having issues getting a small spirit/qi grammar to compile. The build stack trace is fugly enought to not make any sense to me (despite some assertion_failed i could notice in there but that didn't brought much information)
the input grammar header:
inputGrammar.h
#include <boost/config/warning_disable…

Now, seriously... I'll refrain from using bad words here because we're talking about the Boost fellows. It MUST be my mistake to see things this way, but I can't understand why, so I'll ask it here; maybe someone can enlighten me in this matter. Here it goes:
uBLAS has this nice class template called…

Erm. I hope I am seriously overlooking something.
I want to rotate a 2d vector (kartesian) v by a certain angle phi.
I can't find a function that generates the appropriate matrix
or just performs that function.
I know how to do this by hand. I am looking for a ublas utility "something"
that does…

I'm writing an OpenGL program where I compute my own matrices and pass them to shaders. I want to use Boost's uBLAS library for the matrices, but I have little idea how to get a uBLAS matrix into OpenGL's shader uniform functions.
matrix<GLfloat, column_major> projection(4, 4);
// Fill matrix

hello.
I am seeking advice on design/general idea on how to force matrix dimension constraints on ublas matrix/vector possibly using boost units.
For example, let matrix A have dimensions of time x force (for example)
// does not have dimensions, time x force and force x time are not distinguished…

hello.
I am baffled by the following name collision:
namespace mp2 {
boost::numeric::ublas::matrix_range<M>
slice(M& m, const R1& r1, const R2& r2) {
namespace ublas = boost::numeric::ublas;
ublas::range r1_(r1.begin(), r1.end()), r2_(r2.begin(), r2.end());
return…
