The entry point to MATLAB C code functions has the signature of the mexFunction function in the code snipped at the bottom of the post. Since I want to essentially pass the ar...
I'm working with arrays of image filepaths. A typical array might have 5 image filepaths stored in it. For each array, I want to pull out just the "best" photo to display as a thumbnail for the collection. I find looping and arrays very confusing and after 4 hours of trying to figure out how to structure this, I'm at a loss. Here are...

... or alternatively an Array which prevents duplicate entries. Is there some kind of object in Ruby which: responds to [], []= and << silently drops duplicate entries is Enumerable (or at least supports find_all) preserves the order in which entries were inserted ? As far as I can tell, an Array supports points 1, 3 and 4; while a Se...
This is such a dumb question it's frustrating even asking it. Please, bear with me, I'm feeling particularly dumb over this one today.... I've got a library with a certain typedef struct. basically: typedef struct {int x; int y;} coords; What I really wanted to do was declare in my header a variable array of this: coords MyCoord...
I have an application that will have 5-15 buttons depending on what is available from a backend. How do I define the proper GridView layout files to include an array of buttons that will each have different text and other attributes?

Splats are cool. They're not just for exploding arrays, although that is fun. They can also cast to Array and flatten arrays (See http://github.com/mischa/splat/tree/master for an exhaustive list of what they do.) It looks like one cannot perform additional operations on the splat, but in 1.8.6/1.9 the following code throws "unexpected ...
