Dimensions[expr] gives a list of the dimensions of expr. Dimensions[expr, n] gives a list of the dimensions of expr down to level n.
OddQ
(Built-in Mathematica Symbol) OddQ[expr] gives True if expr is an odd integer, and False otherwise.
VectorAngle[u, v] gives the angle between the vectors u and v.
HermitianMatrixQ[m] tests whether m is a Hermitian matrix.
SymmetricMatrixQ[m] tests whether m is a symmetric matrix.
PositiveDefiniteMatrixQ[m] tests whether m is a positive definite matrix.
Functionality in this package has been added to the built-in Mathematica kernel. CumulativeSums is replaced by Accumulate. Frequencies is replaced by Tally. BinCounts and ...
Numerical algorithms for constrained nonlinear optimization can be broadly categorized into gradient-based methods and direct search methods. Gradient search methods use ...
The equations of motion for a free rigid body whose center of mass is at the origin are given by the following Euler equations (see [MR99]). Two quadratic first integrals of ...
FindRoot[f, {x, x_0}] searches for a numerical root of f, starting from the point x = x_0.FindRoot[lhs == rhs, {x, x_0}] searches for a numerical solution to the equation lhs ...
