How do you picture a multi dimensional array? Say a single is a line A double is a square A triple is a cube What is a 4th dimension? Also, what would be a practical use for 5+ dimensions?

usually the 4th demesion is precived as time...for example, a point in time and space, can have a length from a geographic point, and height from it, and a depth from it, for 3 dimenstional, but, five years ago or soemthing, the point was not in that location, for an example of 4d. so when you draw something, it is a freeze frame of a particular moment...such as a point in a graph...so to simulate or display a 4th dimension, you would have to have something that was in constant motion, for example, a point changing geographical locations, therfore creating a line, or equation. its not really something thats easy to explain...im not sure what the 5th dimmension is... as for arrays: the way i would picture a 4 dimensional array is multiple cubes, that are kinda "inside" each other, or a cube thats contents continuasly change. again, not sure about the 5th and above dimmensions. hope that helps. just use your imagination, lol, you'll come up with something even crazier that mine! eaw8806

Hey You can't really imagine multidimentions like the way you imagine the three dimentions as three lines prependicular to each other and that's only because we are 3d creatures. It's like asking your shadow (which is a 2d creature) to think of three dimentions. It can't. However you can use the idea of graphs. Q graphs are a sort of reperesting multidimentional cubes. All this said, in terms of programming you don't really need to have apicture of a multidimentional array as multidimentional sapce. Just think of an n dimentional array as a collection of variables where you need n numbers to locate the variable. something like postal code. Hope that helps

Khash Your shadow is a 'creature'??

Sure. why not?

Fun fact: There are some people who can perfectly picture 10 dimensions with ease. It's very uncommon, though.
