Synopsis

Description

In the simplest case, the list of symbols containing the given string is returned.

i1 : apropos "atrix"

o1 = {BlockMatrix, ChangeMatrix, CompactMatrix, compactMatrixForm,
     ------------------------------------------------------------------------
     diagonalMatrix, fillMatrix, genericMatrix, genericSkewMatrix,
     ------------------------------------------------------------------------
     genericSymmetricMatrix, getChangeMatrix, Matrix, matrix,
     ------------------------------------------------------------------------
     MatrixExpression, MinimalMatrix, MutableMatrix, mutableMatrix,
     ------------------------------------------------------------------------
     randomMutableMatrix, submatrix, submatrix', submatrixByDegrees,
     ------------------------------------------------------------------------
     sylvesterMatrix, SyzygyMatrix}

o1 : List

Regular expressions allow for more complicated requests. For example, to find all functions that start with mat or Mat:

i2 : apropos "^[mM]at"

o2 = {match, mathML, Matrix, matrix, MatrixExpression}

o2 : List
