matlab - How do I detect empty cells in a cell array? -


How do I find empty cells in a cell array? I know that the command to remove an empty cell is a (1) = [] , but I think that which cells are empty, can not get MATLAB to automatically detect .

Background: I have already specified a cell table using the a = cell (1,53) . Then i if exists (file name (i)) and textscan to check for a file, and read it, as a result, when filename (i) does not Exists, an empty cell result and we move to the next file

When I finish reading all the files, then I would like to delete the empty cells of a I try if a (i) == []

use 

 % # empty cells Search micro cells = cellfun (@ isempty, a); Empty empty cells # empty (emptyCells) = [];

Note: a (i) == [] will not work if you want to know that the i-th cell is empty, you can see the contents of the cell You have to use curly brackets to reach. In addition, to evaluate == [] instead of true / false , you use the command isempty Instead, in a nutshell: a (i) == [] should be rewritten as isempty (a {i}) .

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....
