Hi, Do a search on FEM, Finite Element Method. Today there are tons of example code using Gaussian elimination. My Masters Thesis (1990:s) was solving any 2D/3D Trusses using FEM. It took me less than 50 lines of C code and could solve 20k unknowns. Note: The matrix will be 1/2 full of zeros.

not sure if this issue is relevant to the mailing list: while running the tutorial at https://github.com/balister/oe-gnuradio-manifest which aims at recovering all tools needed to build an image for an embedded architecture, intensive requests to git are performed to fetch all the source codes.

[Discuss-gnuradio] filter taps and delays

2014-01-05 Thread Miklos Maroti
Hi Guys, If I use interp_fir_filter_ccc(3, [1, 2, 3, 4, 5, 6]) on a vector source containing [1, 0, 0, ...] then I get [1, 2, 3, 4, 5, 6, 0, 0, ...] as expected. However, if I use interp_fir_filter_ccc(3, [1, 2, 3, 4, 5]) then I get [0, 1, 2, 3, 4, 5, 0, 0, ...] so the samples are shifted to the
