Multidimensional arrays don't work in TS. There was a brief discussion on
that just
short time ago. From whatever you are describing you probably don't need
an MD
array. If you just want to capture data and its 5 attributes a 2D array
will do just fine.
If you need more you can use 3 2D arrays.
>From your declaration I see you want to do 10x10x1001x6. This is a 4D and
is
pretty hard to understand what you are trying to do.
If you can describe what you are trying to do in detail I might
be able to give you some pointers. As far as sorting I have to warn you
again about
MD - it could be a nightmare trying to do that in MD. Plus with 1001 cells
its
gonna take some time to sort. But should not be a problem in 2D.
You've mentioned " for plotting ".Plotting in where? As far as
complexity, arrays are
the upper limit of EL programming. This is just about the most compacted
of EL.
It you can do arrays in EL you can do the rest. Overall arrays are not
hard at all.
You basically write a pointer to point to the right cell. Actually two
pointers, for
rows and columns. I think I have some sample code on 2D array writing,
sorting,
appending, printing. Let me know if interested. I can dig it out for you.
This will
basically tell you all you need to know about 2D arrays in one EL study.
I personally use arrays in my work, for instance in my Statistical module
to
capture the statistical footprint of the market. Works well. Takes a var,
accumulates its frequency distribution, calculates density, stores it,
sorts it,
does min, max, mean, median, range, std, etc., stores'em, appends to an
ascii file and
prints to a print log. So you aint the only one doing the arrays.
