The GNU Scientific Library is a powerful c,c++ math repository. It covers a wide range of facets, and the code is highly efficient and rich in interfaces. This library was found in a recent project where multiple Gaussian distributions were used.

The eigenvalues and eigenvectors of matrices are a very important concept in linear algebra and matrix theory. It is also frequently used in the field of remote sensing. For example, the principal component analysis of multispectral and

The eigenvalues and eigenvectors of matrices are a very important concept in linear algebra and matrix theory. In the field of remote sensing, for example, the principal component analysis of multispectral and hyperspectral images requires the
