Constructing matrices with special shapes. This creates a matrix of 0s containing a radius 4 diamond of 1s. The result is a 9×9 matrix. The size of the matrix can be ...

A three-dimensional coordinate system assigns three numbers to each point in space. In defining a coordinate system, you have to make a choice about what to measure and how ...

When you write programs in Mathematica, there are various ways to document your code. As always, by far the best thing is to write clear code, and to name the objects you ...

Built on powerful and elegant principles, the core Mathematica language provides a uniquely deep and rich programming language that scales from rapid prototyping to large ...

Evaluate[expr] causes expr to be evaluated even if it appears as the argument of a function whose attributes specify that it should be held unevaluated.

PlotFlag is an option to MiniMaxApproximation and GeneralMiniMaxApproximation that specifies whether plots of the relative error of successive iterates in the approximation ...
