Functions

ivec itpp::find (const bvec &invector)
 Return a integer vector with indicies where bvec == 1.
vec itpp::impulse (int size)
 Impulse vector.
vec itpp::linspace (double from, double to, int length=100)
 Linspace (works in the same way as the matlab version).
vec itpp::zigzag_space (double t0, double t1, int K=5)
 Zig-zag space function (variation on linspace).
imat itpp::hadamard (int size)
 Hadamard matrix.
