In Mathematica , many kinds of data are stored in tables or lists. Mathematica provides many useful functions for creating and manipulating these tables.
ImageFilter[f, image, r] applies the function f to the range r neighborhood of each pixel in each channel of image.
SpheroidalEigenvalue[n, m, \[Gamma]] gives the spheroidal eigenvalue with degree n and order m.
Converting between strings and lists of characters. This gives a list of the characters in the string. You can apply standard list manipulation operations to this list.
Cancel
(Built-in Mathematica Symbol) Cancel[expr] cancels out common factors in the numerator and denominator of expr.
ExpandDenominator[expr] expands out products and powers that appear as denominators in expr.
StringPosition["string", " sub"] gives a list of the starting and ending character positions at which " sub" appears as a substring of " string". StringPosition["string", ...
