single-precision transforms will most likely not be faster than their
|
||||
double-precision counterparts, but they will require significantly less
|
||||
memory.
|
||||
|
||||
Two example and benchmark programs are distributed with libsharp:
|
||||
<ul>
|
||||
<li>sharp_test.c checks the accuracy of the (iterative) map analysis
|
||||
algorithm</li>
|
||||
<li>sharp_bench.c determines the quickest transform strategy for a given
|
||||
SHT</li>
|
||||
</ul>
