## 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.
imat | itpp::jacobsthal (int p)
| Jacobsthal matrix.
imat | itpp::conference (int n)
| Conference matrix.
const cmat | itpp::toeplitz (const cvec &c)
| Generate symmetric Toeplitz matrix from vector `c` (complex valued)
mat | itpp::rotation_matrix (int dim, int plane1, int plane2, double angle)
| Create a rotation matrix that rotates the given plane `angle` radians. Note that the order of the planes are important!
void | itpp::house (const vec &x, vec &v, double &beta)
| Calcualte the Householder vector.
void | itpp::givens (double a, double b, double &c, double &s)
| Calculate the Givens rotation values.

| Template instantiation of eye.
template void | itpp::eye (int, bmat &)
| Template instantiation of eye.
template void | itpp::eye (int, imat &)
| Template instantiation of eye.
template void | itpp::eye (int, cmat &)
| Template instantiation of eye.
template vec | itpp::linspace_fixed_step (double, double, double)
