Python implementation of the TT-Toolbox
When constructing a TT matrix from an Hamiltonian operator with a very large number of degrees of freedom the norm of the matrices passed to the QR factorization routine becomes...
I was able to use the conda recipe after prepending the following line in build.sh `export LDFLAGS="-undefined dynamic_lookup -bundle"` Without -undefined dynamic_lookup the linker will complain about missing symbols. The...
This error occurs in the latest anaconda builds. How I have repaired it on my computer: **1) Updated numpy and scipy** _conda update numpy conda update scipy_ **2) Installed accelerate...
Hi! I'm trying to run `!pip install ttpy` but I'm facing some problems in my laptop and in Colab. The error in my laptop is the following:  And in...
`amen_mv` weirdly exceeds number of sweeps limit when working with some complex-valued matrices and vectors. Here is the simplest example I could find: ```python d = 3 x = tt.rand(2,...
#### Main Contributions - Add `tt.interpolate` for common routines (Chebyshev and splines) for interpolation in TT-format. - Implement Fokker-Plank equation solver in `ttpy` based on original implementation [fpcross][1] in [teneva][2]....
After adding a random tt of rank 5+ as noise to a tt with rank 1 to reach a rank of 6+, when ksl propagates it on docker, the rank...
Bridging layer [`tt/core/tt_f90.f90`][0] between `ttpy` and `tt-fort` uses global variables `core` and `zcore` which are used to convert cores from [single array format][1] to [array-per-core representation][2] and vice versa which...
