InputStream["name", n] is an object that represents an input stream for functions such as Read and Find.
LaguerreL[n, x] gives the Laguerre polynomial L_n (x). LaguerreL[n, a, x] gives the generalized Laguerre polynomial L_n^a(x).
LegendreQ[n, z] gives the Legendre function of the second kind Q_n (z). LegendreQ[n, m, z] gives the associated Legendre function of the second kind Q_n^m(z).
LinkInterrupt[link] sends an interrupt to the program at the other end of the specified MathLink connection.
MapAt
(Built-in Mathematica Symbol) MapAt[f, expr, n] applies f to the element at position n in expr. If n is negative, the position is counted from the end. MapAt[f, expr, {i, j, ...}] applies f to the part of ...
MatrixRank[m] gives the rank of the matrix m.
MorphologicalTransform[image, f] applies the function f to the 3*3 neighborhood of each pixel in a binary image image.MorphologicalTransform[image, rule] applies a ...
Needs
(Built-in Mathematica Symbol) Needs["context`"] loads an appropriate file if the specified context is not already in $Packages. Needs["context`", " file"] loads file if the specified context is not ...
NotebookClose[notebook] closes the notebook corresponding to the specified notebook object. NotebookClose[] closes the current evaluation notebook.
Null
(Built-in Mathematica Symbol) Null is a symbol used to indicate the absence of an expression or a result. It is not displayed in ordinary output. When Null appears as a complete output expression, no ...
