Properties of Strings Operations on Strings Characters in Strings

MathLink allows you to exchange data of any type with external programs. For more common types of data, you simply need to give appropriate :ArgumentTypes: or :ReturnType: ...

NeighborhoodGraph[g, v] gives the graph neighborhood vertex v in the graph g. NeighborhoodGraph[g, {a_1, a_2, ...}] gives the graph neighborhood of the a_i that can be ...

Mathematica's symbolic architecture supports a highly generalized notion of assignment, in which you can specify a transformation for any class of expressions defined by a ...

BitOr[n_1, n_2, ...] gives the bitwise OR of the integers n_i.

BoxMatrix[r] gives a (2 r + 1)*(2 r + 1) matrix of 1s.BoxMatrix[r, w] gives a (2 r + 1)*(2 r + 1) block of 1s centered in a w*w matrix of 0s.BoxMatrix[{r_1, r_2, ...}, ...] ...

You can manipulate lists of transformation rules in Mathematica just like other symbolic expressions. It is common to assign a name to a rule or set of rules. This assigns ...

The function FindRoot has a Jacobian option; the functions FindMinimum, FindMaximum, and FindFit have a Gradient option; and the "Newton" method has a method option Hessian. ...

If you make a definition like f[x_]:=x Sin[x], Mathematica will store the expression x Sin[x] in a form that can be evaluated for any x. Then when you give a particular value ...

x + y + z represents a sum of terms.
