[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 r

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. Al

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.
