view matrixcomp/seqcheb.m @ 7:e0817ccb2834 draft
Add square root matrix function file, rename atom at funm_files, modify old toolbox to run it inside GNU Octave.
added funm_files/fun_atom.m
added sqrtm2.m
added toolbox/gecp.m
toolbox/see.m: comment wrong call to subplot
toolbox/tmtdemo.m: add a cast to double, as eig does not admit bool matrix input
removed funm_files/funm_atom.m

function x = seqcheb(n, k) %SEQCHEB Sequence of points related to Chebyshev polynomials. % X = SEQCHEB(N, K) produces a row vector of length N. % There are two choices: % K = 1: zeros of T_N, (the default) % K = 2: extrema of T_{N-1}, % where T_k is the Chebsyhev polynomial of degree k. if nargin == 1, k = 1; end if k == 1 % Zeros of T_n i = 1:n; j = .5*ones(1,n); x = cos( (i-j) * (pi/n) ); elseif k == 2 % Extrema of T_(n-1) i = 0:n-1; x = cos( i * (pi/(n-1)) ); end
