Extra things to save for fast1 algorithm.
This structure holds things computed during init_fast1 that need to be saved to file separately from the main matrices.
Notes:
An array of length bell_length holding all bell values.
int bell_length |
The total length of all the bells to save.
int* bell_offsets |
A list of integer offsets to use within bell_handle to get particular bells. There are 5*2*num_levels entries. The 2 is for bells and dual bells. The num_levels is because we have different bells for each level The five is for the possible types of bells at each level:
