variables - define array name within a loop -


I am going about it wrongly, but I try to define and fill the array within a loop I am here. 

  xx = tall for i = 0,39 (findgen (n + 1l) * sx + line1x [i]) sz = size (xx) arrayname = 'line' + strtrim (i , 2)) Arrayname = findgen (3, sz [1]) array name [0, *] = xx arrayname [1, *] = yy arrayname [2, *] = virtual end

It will not work clearly, but is there any way to create a new array on every wavelength and use the string set by 'line' + stratim (i, 2) to fill it? In this case my name will be 40 arrays ... ... 39 The hard part here is that SG [1] varies, so I can not simply define a large array by holding everything.

idl 8.0 or later you can use the HASH datatype for this Are there.

Your code will look like this: for ii = 0,39 array_dict = hash () xx = tall (findgen (n + 1l) * sx + line1x [ii ]) Sz = size (xx) arrayname = 'line' + string (1, FORMAT = '(I02)' array = findgen (3, sz [1]) array [0, *] = xx array [1, *] = Yy array [2, *] = vertline array_dict [arrayname] = endfor for the array

You can now use your arrays by name: 

 < Code> line = array_dict ['line01']

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
