h5::array_stack : stacking arrays or scalars
|
|
================================================================
|
|
|
|
h5::array_stack writes a sequences of arrays of the same shape (or of scalars) into an hdf5 array with one more dimension, unlimited in the stacking direction.
|
|
|
|
It is typically used to store a Monte-Carlo data series for later analysis.
|
|
|
|
* If the base of the stack is an array of rank R, the resulting hdf5 array will be of rank R+1.
|
|
|
|
* If the base of the stack is a simple number (double, int, ...), R=0.
|
|
|
|
* The syntax is simple :
|
|
|
|
* The << operator piles up an array/scalar onto the stack.
|
|
* The ++ operator advances by one slice in the stack.
|
|
* The () operator returns a view on the current slice of the stack.
|
|
|
|
* The stack is bufferized in memory (`bufsize` parameter), so that the file access does not happen too often.
|
|
|
|
* NB : beware to complex numbers ---> REF TO COMPLEX
