Interesting MATLAB Tricks and Trivia

I used to have a large list of "obscure and/or tricky" MATLAB stuff on my Stack Overflow profile.  It got a bit long.  So here is the new home of my evolving list of awesome MATLAB trivia:

My favorite obscure and/or tricky MATLAB stuff:

• Beware of negative zero! (I blogged about this here too.)
• Bizarre end semantics.
• Super efficient N-D Cartesian product.  Explained nicely by Luis Mendo (give that  man a vote!).
• Dynamic legend.
• The colon operator can be passed as a character! Like this, x(':',end).
• colon is smart! The syntax j:i:k does not always create an array that goes to k; it goes to j+m*i, where m = fix((k-j)/i);.
• sprintfc: print into a cell array.
• The for loop expression (for var = expr ...) can be a matrix, looping through columns.
• Most operators have named functional forms.
• Set membership tests for sorted arrays: ismembc, ismembc2, and more.
• You can make a DllMain for a MEX file to implement attach/detach instructions, and mexAtExit for module unload ops.
• How does dynamic array resizing/growth (possibly) work?
• Where does guidata "hide" the handles structure (and other GUI data tricks)?.
• Changing the order of line series colors (ColorOrder), and the "best" colors.
• What does MATLAB do internally when you truncate an array with Z(end-N:end)=[];?
• Why don't they add 0 based indexing to MATLAB (according to Cleve Moler)?
• Apparently MathWorks did not expect anyone to actually overload curly braces ({}).
• accumarray rocks, but you have to use it right.
• The default C MEX configuration uses ANSI C, which really stinks. Enable C99.  This one irritates me because people pretend like they can't just TURN IT ON!
• bsxfun can replicate in multiple dimensions.
• Use kron to replicate either array elements or whole arrays.

I'm a research scientist focused on medical image processing, machine learning, dimensionality reduction, and parallel computing. I ♥ `accumarray`.
