Abstract：Based on the sparse matrix decomposltion expression of coefficient matrix in discrete Y transform[1],we progran1ed fast Y transform (FYT) algorithm by using Turbo pascal language. FYT algorithm was then tested under the Turbo-87 system in IBM personal computer. In the computation of discrete Fourier transform,FYT algorithrn brings rnore efficient and more accurate result and takes 20% time less than FFT algorithm does.
