Whenever machine-precision numbers appear in a calculation, the whole calculation is typically done in machine precision. Mathematica will then give machine-precision numbers ...

Matrix inversion. Here is a simple 2×2 matrix. This gives the inverse of m. In producing this formula, Mathematica implicitly assumes that the determinant ad-bc is nonzero.

Mathematica always allows you to refer to special characters by using names such as ∖[Alpha] or explicit hexadecimal codes such as ∖:03b1. And when Mathematica writes out ...

Many large-scale applications of linear algebra involve matrices that have many elements, but comparatively few that are nonzero. You can represent such sparse matrices ...

Mathematica provides a simple and consistent method for accessing and using files. In addition to inserting a file path that is specific to your operating system, Mathematica ...

Since lists are just a particular kind of expression, it will come as no surprise that you can refer to parts of any expression much as you refer to parts of a list. This ...

StationaryWaveletTransform[data] gives the stationary wavelet transform (SWT) of an array of data.StationaryWaveletTransform[data, wave] gives the stationary wavelet ...

 

This example illustrates how to use modal dialogs initiated from another window, optionally setting up property values on widgets in the modal dialog, and, when the modal ...
