Meschach computes fast fourier transforms, extracts columns and rows, and computes eigenvalues of symmetric matrices meschach能计算快速傅立叶变换(fastfouriertransform)、提取列和行以及计算对称矩阵的特征值。
Meschach was designed to solve systems of dense or sparse linear equations, compute eigenvalues and eigenvectors, and solve least squares problems, among other things meschach可以解稠密或稀疏线性方程组、计算特征值和特征向量和解最小平方问题,另外还有其它功能。
