FloatDST_1D (math 11.1.0 API)

java.lang.Object
- de.gsi.math.spectra.dst.FloatDST_1D

```
public class FloatDST_1D
extends java.lang.Object
```
Computes 1D Discrete Sine Transform (DST) of single precision data. The size of data can be an arbitrary number. It uses DCT algorithm. This is a parallel implementation optimized for SMP systems.
