Documentation

Vector object.

int n

Size of the vector

real* ptr

Data of the vector

Vec(real* ptr_, int n_dim)

Create a vector from values in ptr_. (No memory copy).

Vec(int n_dim)

Create a new vector

void copy(Vec* vec, int start_i = 0)

Copy the vector vec starting from index start_i

void zero()

Zero the matrix

real norm1(Vec* weights = NULL)

Compute the norm1

real norm2(Vec* weights = NULL)

Compute the norm2

real normInf()

Compute the norm inf

real iP(Vec* vec, int start_i = 0)

Inner product of two vectors from start_i downwards

Vec* subVec(int dim1, int dim2)

Return a sub-vector. Note that the memory is shared with the original vector, so *be carefull*.

This class has no child classes.
