meschach computes fast fourier transforms, extracts columns and rows, and computes eigenvalues of symmetric matrices meschach能計算快速傅立葉變換(fastfouriertransform)、提取列和行以及計算對稱矩陣的特征值。
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可以解稠密或稀疏線性方程組、計算特征值和特征向量和解最小平方問題,另外還有其它功能。
