% Mathematical aliases -- algebraic shorthand   
%   oneover       - Returns reciprocal of argument.
%   frac          - Make fraction: FRAC(A,B)=A./B
%   twopi         - Raise (2 pi) to the specified power.
%   res           - Residual after flooring:  RES(X)=X-FLOOR(X)
%   squared       - Squares its argument:  SQUARED(X)=X.^2
%   cdot          - Dot product:  CDOT(A,B)=REAL(A.*CONJ(B))
%   rot           - Complex-valued rotation:  ROT(X)=EXP(SQRT(-1)*X)
%   choose        - Binomial coefficient: CHOOSE(N,K) = "N choose K"
%
% Boolean expressions, sets, and slabs
%   subset        - Extract subset of A given B.  
%   lookup        - Locate elements of one array within another.
%   ismemb        - Tests whether the elements of an array are members of a set.
%   iscompat      - Tests whether an array's size is "compatible" with another's.
%   numslabs      - Counts the number of 'slabs' of one array relative to another.
%
% Other
%   quadform      - Implements the quadratic formula.
%
% Angles, degrees, and radians
%   relog         - RELOG(X)=REAL(LOG(X))
%   imlog         - IMLOG(X)=UNWRAP(IMAG(LOG(X)))
%   jrad2deg       - Converts radians to degrees.
%   jdeg2rad       - Converts degrees to radians.
