The theoretical analysis and computational implementation of factorization-based methods for the numerical solution of linear boundary value problems for ordinary differential equations are presented.

Nyström's method with the trapezoidal rule, and the Fourier method, produce the same approximation to the solution of an integral equation at the collocation points ...

Mg isotope compositions of some typical geological standard samples measured by the DS method and the SSB method in different laboratories. The sample-standard-bracketing (SSB) method and double-spike ...
