vector_int::vector_int ( const size_t &  n,
bool  clear = true 
)

Class constructor with specified vector size.

Parameters:
n: number of entries
clear: flag if true then This function allocates memory for a matrix of size new_rows rows by new_cols columns and initializes all the elements of the matrix to zero (does a calloc), if false then creates a matrix of size new_rows by new_cols, returns a pointer to a gsl matrix struct (does an alloc).

If clear is not specified then default is clear = true.
