     Convenient (but no faster) replacement of for loops:
       fevalArrays       - Used to apply the same operation to a stack of array elements.
       fevalDistr        - Run simple jobs locally or in distributed fashion using queue.
       fevalImages       - Used to apply the same operation to all images in given directory.
       fevalMats         - Used to apply the same operation to all .mat files in given directory.

     Timing:
       ticStatus         - Used to display the progress of a long process.
       tocStatus         - Used to display the progress of a long process.

     Array manipulation:
       arrayCrop         - Used to crop a rectangular region from an n dimensional array.
       arrayToDims       - Pads or crops I appropriately so that size(IC)==dims.
       cell2array        - Flattens a cell array of regular arrays into a regular array.
       mat2cell2         - Break matrix up into a cell array of same sized matrices.

     Display:
       c                 - clc - clear command window.
       cc                - close all, clc
       ccc               - clear, close all, clc, clear global
       char2img          - Convert ascii text to a binary image using pre-computed templates.
       dispMatrixIm      - Display a Matrix with non-negative entries in image form.
       figureResized     - Creates a figures that takes up certain area of screen.
       imLabel           - Improved method for labeling figure axes.
       plotEllipse       - Adds an ellipse to the current plot.
       plotGaussEllipses - Plots 2D ellipses derived from 2D Gaussians specified by mus & Cs.
       text2             - Wrapper for text.m that ensures displayed text fits in figure.
       txt2img           - Convert text string to a binary image.

     Miscellaneous:
       checkNumArgs      - Helper utility for checking numeric vector arguments.
       dijkstra          - Runs Dijkstra's shortest path algorithm on a distance matrix.
       dirSynch          - Synchronize two directory trees (or show differences between them).
       gauss2ellipse     - Creates an ellipse representing the 2D Gaussian distribution.
       getPrmDflt        - Helper to set default values (if not already set) of parameter struct.
       ind2sub2          - Improved version of ind2sub.
       isfield2          - Similar to isfield but also test whether fields are initialized.
       int2str2          - Convert integer to string of given length; improved version of int2str.
       multiDiv          - Matrix divide each submatrix of two 3D arrays without looping.
       multiTimes        - Matrix multiply each submatrix of two 3D arrays without looping.
       normpdf2          - Normal prob. density function (pdf) with arbitrary covariance matrix.

       randint2          - Faster but restricted version of randint.
       randSample        - Generate values sampled uniformly without replacement from 1:n.
       rotationMatrix    - Performs different operations dealing with a rotation matrix
       simpleCache       - A simple cache that can be used to store results of computations.
       spBlkDiag         - Creates a sparse block diagonal matrix from a 3D array.

       subsToArray       - Converts subs/vals image representation to array representation.
       subsampleMatrix   - Samples elements of X so result uses at most maxMegs megabytes of memory.
       uniqueColors      - Generate m*n visually distinct RGB colors suitable for display.

     Thin plate splines:
       tpsGetWarp        - Given two sets of corresponding points, calculates warp between them.
