Description: LAPACK是用Fortran90和规定套路解决系统同步线性方程组，最小二乘解线性方程组，特征值问题，以及奇异值问题。相关的矩阵分解（陆，乔莱斯基，快速反应，分解，舒尔，广义Schur ）也提供了，因为有关的计算，如重新安排的舒尔分解和估计条件号码。致密带状矩阵的处理，而不是一般稀疏矩阵。在所有领域，类似的功能是提供真正的和复杂的矩阵，在单，双精度-LAPACK is written in Fortran90 and provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems. The associated matrix factorizations (LU, Cholesky, QR, SVD, Schur, generalized Schur) are also provided, as are related computations such as reordering of the Schur factorizations and estimating condition numbers. Dense and banded matrices are handled, but not general sparse matrices. In all areas, similar functionality is provided for real and complex matrices, in both single and double precision

Description: 该程序可以测试人脸的二维的区间矩阵的稳定性。详细说明见英文说明-The program can test the stability of 2-D face of an interval matrix.
By relying on a two-dimensional (2-D) face test, Ref [1,2] obtained a necessary and sufficient condition for the robust Hurwitz and Schur stability of interval matrices. Ref [1,2] revealed that it is impossible that there are some isolated unstable points in the parameter space of the matrix family, so the stability of exposed 2-D faces of an interval matrix guarantees stability of the matrix family. This program provides the examples to demonstrate the applicability of the robust stability test of interval matrices in Ref [1, 2].
Remarks:
(1) The 2-D face of an interval matrix is Hurwitz stable, if and only if the maximum real part of the eigenvalues of the 2-D face of the interval matrix is smaller than 0 [1].
(2) An interval matrix is Hurwitz stable, if and only if all the 2-D faces of the interval matrix is Hurwitz stable.
(3) The 2-D face of an interval matrix is Schur stable, if and only if the maxi

Description: 长期预测(LTP)与规则脉冲激励(RPE),而全速率编解码器就被称为RPE-LTP线性预测编码器。
输入至RPE-LTP编码器的数据为包括160个采样值的20ms语音,每一个采样值都拥有13位精度。数据首先通过预加重滤波器来提高信号的高频分量,以获得更好的传输效率。滤波器一般还消除信号上的任何偏移以简化进一步的计算。
正如前面所提到的,语音产生模型可看成是空气通过一组不同大小的圆柱体。短期分析级采用自动相关来计算与模型所用的8个圆柱体有关的8个反射系数,同时采用一种称为Schur递归的技术来有效地求解所得到的方程组。参数被变换成可以更少的位数来进行更佳量化的LAR(log-area ratio)。这些是传输流的前8个参数。
然后再将编码后的LAR解码成系数,并用来对输入采样值进行滤波。解码LAR的原因是为了确保编码器使用解码器上的相同信息来进行滤波。这一级上的其余采样值用于编解码器的LTP级。

Wave transformation and 4 *4 block Schur decomposition of the low frequency part are carried out. Then the binary values are obtained by using the stability of the coefficient difference of the subblock unitary matrix.
The watermark information is embedded into the carrier QR code adaptively. Finally, the watermark information is extracted by scanning the watermark QR code. At the same time, the algorithm achieves blind extraction. Results The algorithm can resist the attack of print and scan, and can resist Gaussian noise, salt and pepper noise, speckle noise, Poisson noise.
