% JARRAY   Vector, matrix, and N-D array tools.
%
% Vector and matrix multiplication
%   oprod         - Outer product of two column vectors. 
%   osum          - Outer sum of two column vectors.
%   vectmult      - Matrix multiplication for arrays of two-vectors. 
%   vectmult3     - Matrix multiplication for arrays of three-vectors.
%   offset        - Offsets matrix rows or columns.
%   matmult       - Matrix multiplication for arrays of 2 x 2 matrices. 
%
% Array transformation and reduction
%   row2col       - Given any vector, returns it as a column vector.
%   col2row       - Given any vector, returns it as a row vector.
%   nonnan        - Return all non-NAN elements of an array.
%   finite        - Return all finite elements of an array.
%
% Multidimensional (N-D) array tools
%   nd            - Number of the last nonsingleton dimension.
%   nnsd          - Number of nonsingleton dimensions.
%   ndtrans       - Generalized transpose of a potentially multidimensional vector.
%   ndrep         - Replicates an array along a specified dimension.
%   ndindex       - Indexes a multidimensional array along a specified dimension
%
% Array tests
%   aresame       - Tests whether two N-D arrays are the same.
%   iscol         - Tests whether the argument is a column vector.
%   isrow         - Tests whether the argument is a row vector.
%   iseven        - Tests whether the elements of an array are even.
%   isodd         - Tests whether the elements of an array are odd.
%   ismat         - Tests whether the argument is a 2-D matrix; false for scalars.
%   issing        - Tests whether the argument is a singleton array.
%   issquare      - Tests whether the argument is a square matrix.
%   islargest     - True for the largest-magnitude element at each index location.
%   turningpoint  - True for turning points, i.e. local extrema, along rows.
%
% Array operation aliases -- min, max, etc.
%   allall        - ALLALL(X)=ALL(X(:))
%   maxmax        - MAXMAX(X)=MAX(X(:))
%   minmin        - MINMIN(X)=MIN(X(:))
%   anyany        - ANYANY(X)=ALL(X(:))
%   sumsum        - SUMSUM(X)=SUM(X(:))
%   range         - RANGE(X)=[MIN(X(:)) MAX(X(:))]
%
% Indexing (subscripting) 
%   indexor       - Finds the union of multiple indices.
%   indexand      - Finds the intersection of multiple indices.
%   crossings     - Find values of an array crossing a specified threshold.
%
% Interpolation
%   jinterp       - Matrix-matrix 1-D interpolation.
%   doublen       - Interpolates a time series to double its length.
%   sinterp       - Spline-interpolates a column vector to a new length.
%   fillbad       - Linearly interpolate over bad data points. 
%   quadinterp    - Fast quadratic interpolation for arbitrary-sized arrays.
%   cubeinterp    - Fast cubic interpolation for arbitrary-sized arrays.
%
% Smoothing
%   smartsmooth   - Fast light smoothing for large matrices.
