Change the dimension of the vector to N. The reserved memory for this vector remains unchanged if possible, to make things faster, but this may waste some memory, so take this in the back of your head. However, if N==0 all memory is freed, i.e. if you want to resize the vector and release the memory not needed, you have to first call init(0) and then init(N). This cited behaviour is analogous to that of the STL containers.

On fast==false, the vector is filled by zeros.
