NEXUS phylogenetic file format. Commonly used for storage and exchange of phylogenetic data. Can store DNA and protein sequences, taxa distances, alignment scores, and ...

Unless f is a flat function, a pattern like f[x_,y_] stands only for instances of the function with exactly two arguments. Sometimes you need to set up patterns that can ...

Evaluating sums. Mathematica recognizes this as the power series expansion of e^x. This sum comes out in terms of a Bessel function.

Mathematica can import—and often export—standard formats used in chemistry, molecular biology and bioinformatics, routinely handling a full range of molecular types, as well ...

FlattenAt[list, n] flattens out a sublist that appears as the n\[Null] th element of list. If n is negative, the position is counted from the end. FlattenAt[expr, {i, j, ...

Mathematica can handle numbers of essentially unlimited length, in any base, using state-of-the-art platform-optimized algorithms, including several developed at Wolfram ...

BinaryReadList["file"] reads all remaining bytes from a file, and returns them as a list of integers from 0 to 255. BinaryReadList["file", type] reads objects of the ...

Mathematica automatically handles both numeric and symbolic matrices, seamlessly switching among large numbers of highly-optimized algorithms. Using many original methods, ...

Version 6.0 represented a major step forward in visualization and graphics, with many new and original concepts. Among them was full integration of Mathematica symbolic ...

Huge numerical datasets are routine for Mathematica. Its powerful array primitives make large-scale array manipulation both easy to specify and highly efficient. And its ...
