% VTOOLS  Operations on multiple data arrays simultaneously.
%
% Adding, multiplying, filtering
%   vadd       - Vector-matrix addition without "dimensional" hassle. 
%   vmult      - Vector-matrix multiplication without "dimensional" hassle.
%   vfilt      - Filtering along rows without change in length.
%   vdiff      - Length-preserving first central difference. 
%   vpower     - Raises array to the specified power.
%   
% Dimensions, sums, moments
%   vnd        - Number of dimensions. 
%   vsize      - Returns the sizes of multiple arguments.
%   vsum       - Sum over finite elements along a specified dimension.
%   vmean      - Mean over finite elements along a specified dimension.
%   vstd       - Standard deviation over finite elements along a specfied dimension.
%   vmoment    - Central moment over finite elements along a specfied dimension.    
%   vmedian    - Median over finite elements along a specified dimension.
%
% Indexing, shifting, swapping
%   vindex     - Indexes an N-D array along a specified dimension. 
%   vrep       - Replicates an array along a specified dimension.                   
%   vshift     - Cycles the elements of an array along a specified dimension.       
%   vsqueeze   - Squeezes multiple input arguments simultaneously. 
%   vswap      - Swap one value for another in input arrays.
%   vcolon     - Condenses its arguments, like X(:).                           
%   vcellcat   - Concatenates cell arrays of column vectors.
%
% Initializing
%   vempty     - Initializes multiple variables to empty sets.
%   vzeros     - Initializes multiple variables to arrays of zeros.
%
% Datasets of non-uniform length: column / matrix / cell conversions. 
%   colbreaks     - Insert NANs into discontinuties in a vector.
%   mat2col       - Compress NAN-padded matrix data into long columns.
%   col2mat       - Expands 'column-appended' data into a matrix.
%   cell2col      - Converts cell arrays of column vectors into 'column-appended' data.
%   col2cell      - Converts 'column-appended' data into cell arrays of column vectors.
