Wavelet Analysis (Mathematica Guide)

Wavelets are short wavelike functions that can be scaled and translated. Wavelet transforms take any signal and express it in terms of scaled and translated wavelets. The ...

AffineTransform (Built-in Mathematica Symbol)

AffineTransform[m] gives a TransformationFunction that represents an affine transform that maps r to m.r. AffineTransform[{m, v}] gives an affine transform that maps r to m.r ...

Cross (Built-in Mathematica Symbol)

Cross[a, b] gives the vector cross product of a and b.

Equivalent (Built-in Mathematica Symbol)

Equivalent[e_1, e_2, ...] represents the logical equivalence e_1 \[DoubleLeftRightArrow] e_2 \[DoubleLeftRightArrow] ..., giving True when all of the e_i are the same.

IdentityMatrix (Built-in Mathematica Symbol)

IdentityMatrix[n] gives the n*n identity matrix.

MatchingDissimilarity (Built-in Mathematica Symbol)

MatchingDissimilarity[u, v] gives the matching dissimilarity between Boolean vectors u and v.

MatrixQ (Built-in Mathematica Symbol)

MatrixQ[expr] gives True if expr is a list of lists or a two-dimensional SparseArray object that can represent a matrix, and gives False otherwise. MatrixQ[expr, test] gives ...

SymmetricMatrixQ (Built-in Mathematica Symbol)

SymmetricMatrixQ[m] tests whether m is a symmetric matrix.

Times (Built-in Mathematica Symbol)

x*y*z, x*y*z, or x y z represents a product of terms.

Tr (Built-in Mathematica Symbol)

Tr[list] finds the trace of the matrix or tensor list. Tr[list, f] finds a generalized trace, combining terms with f instead of Plus. Tr[list, f, n] goes down to level n in ...
