or you can call cmake on the command-line and have it provide compile & link flags (CXXFLAGS & LDFLAGS typically), see e.g. https://github.com/symengine/symengine/wiki/Using-SymEngine-from-a-Cpp-project
Hi all! I was curious about how expressions are represented internally in symengine so I started browsing the source code. It looks like every expression is always canonicalized before it's stored in, say an
Add or a Mul object. So for example (a + b) * (c + d) wouldn't be represented that way internally, it would first be expanded to a * c + ...etc. Is that impression correct or is there something I've missed?
Sorry if this is documented somewhere obvious, I didn't see anything on the sympy website
x + x is canonicalized to 2*x
Hi, I am trying to build symengine on windows on my MSYS shell. I ran the
On running
cmake command successfully with -DGMP_LIBRARY="c:/.../lib -DGMP_INCLUDE_DIR="c:/.../lib" -DCMAKE_BUILD_TYPE="Debug" where it was able to find the directory of the manually built gmp library.On running
make it fails, throwing cannot find C:/gmp/lib: Permission denied, which is weird since it exists & is accessible .
Any ideas on what it could be?
with the command cout << *x << endl; it triggers a breakpoint in basic-inl.h in line 97
and throws the exception: Unhandled exception at 0x00007FFC1F796AFB (ntdll.dll) in Test-symengine.exe: 0xC0000005: Access violation reading location 0x0000000000000009.
Hey! I enjoy mathematics and programming, and I wish to learn more computational algebra --- in particular, computational group theory and ring theory. Is there an interest for Symengine to have algorithms to compute with permutation groups? How about ring algorithms? (eg. grobner basis computation and the like)?
-- Could NOT find SymEngine (missing: SymEngine_DIR)
This is what my
CMakeLists.txt contains
cmake_minimum_required(VERSION 3.15.5)
find_package(SymEngine 0.8.1 CONFIG PATHS ~/.conan/data/symengine/0.8.1)
set(CMAKE_CXX_FLAGS_RELEASE ${CMAKE_CXX_FLAGS_RELEASE} "-std=c++0x")
include_directories(${SYMENGINE_INCLUDE_DIRS})
add_executable(example main_example.cpp)
target_link_libraries(example ${SYMENGINE_LIBRARIES})
Am I missing something in order for
cmake to find symengine? I used conan to install symengine
You can also do
vec_basic vec;
vec.push_back(integer(1));
vec.push_back(symbol("b"));
vec.push_back(symbol("c"));
DenseMatrix A = DenseMatrix(3, 3, vec);
Ok, so I installed miniconda and installed the symengine successfully(all following the instructions from github and the install page). but when I try to run the command conda env create -f symedocs.ymlit returns what I think it's an error message, the following:
EnvironmentFileNotFound: 'C:\Users\me\miniconda3\symedocs.yml' file not foundI tried creating the file manually and searching for solutions online but wasn't successfull
I think my problem is with anaconda but as I said, I couldn't find a solution so far
I think you can see by the file path but I'm using windows, I think this might be relevant
@Rafael-Conde, that file is at https://raw.githubusercontent.com/symengine/symengine.github.io/sources/symedocs.yml, but that is needed only if you want to build the docs
you can just do
conda install python-symengine if you don't want to build the docs yourself
Or even
pip install symengine
what language do you want use symengine from?
but one last question

conda install xeus-cling notebook
