how do I convert kfr::univector<float> and kfr::univector2d<float> to std::vector<float> and std::vector<std::vector<float>>??
I am using kfr as an extern library, and need to expose my interface using std::vector to avoid integrate kfr in my package. How should I do the convertion?
univector does not use std::allocator by default, so you can not simply assign it to std::vector. However, you can get a univector from std::vector via make_univector. You may use std::allocator by defining KFR_USE_STD_ALLOCATION according to sources.
Pardon my ignorance, as I'm still a C++ novice. I have my own application that uses libraries that only work with std::vector, but I'd like to use KFR to do some of my DSP functions. Is there not a way to convert from std::univector back to std::vector? Also, the make_univector function appears to want double* as input and not std::vector, so can make_univector just take in a variable directly say of type std::vectorstd:float?

Please read the docs at https://www.kfrlib.com/newdocs/types/
univector is a std::vector sort of.
std::vector
std::copy(vector.begin(),vector,end(),uni.begin())
univector2D is just a vector of vectors
univector is std::vector internally but it uses a custom allocator that ensures that memory is properly aligned (cache line alignment is default). Instances of std::vector with different allocators are not directly assignable by C++ standards.
Another way to use std::vector in KFR is to wrap it in a univector_ref using make_univector function. The data will be used directly without redundant copies. This works for both reading and writing external data in KFR functions.
