Abstract
This paper shows an easy to use interface for applying the Discrete Sine Transform (DST) to a vector. This transform is an FFT–related routine and frequently used in many applications, such as, the translation of a class of structured matrices into another class. The ease of use of the interface has been achieved by exploiting the interesting features of the Fortran 90/95 programming language. In addition, a technique has been incorporated to resolve the performance breakdown arising when the vector size cannot be decomposed into small prime numbers. This breakdown stems from the divide–and–conquer type of algorithms used when applying the DST.
