In FFTW (
http://www.fftw.org/), it defines the funciton fftw_malloc to

However, I only want to use new to allocate memory for
std::complex<double>.std::complex<double*p = new std::complex<double>;
/* do stuff with the object */
delete p;
I was asking how to redefine the "new" operator, such that when I call
new std::complex<double>[10]
it will call fftw_malloc function to allocate the memory.

BTW why do you feel you need to dynamically allocate
your object(s) anyway?
For example, the array is defined in an class, and its size is not
fixed.
