If you want to hack your install, you can do it by <pre> edit datatipinfo </pre> then in the nested function sizetype add the following elseif to the big if block on the variable "D" <pre> elseif D == 4 theSize = [num2str(s(1)), 'x', num2str(s(2)), 'x', ... num2str(s(3)), 'x', num2str(s(4))]; else theSize = [num2str(D) '-D']; </pre> I would not recommend hacking this to actually display the value of a 4-dimension variable, it would be too large to fit in the tooltip and needlessly waste memory. @Soren,

I will pass that suggestion on to the editor team. If you want to hack your install, you can do it by

edit datatipinfo

then in the nested function sizetype add the following elseif to the big if block on the variable “D”

 elseif D == 4
            theSize = [num2str(s(1)), 'x', num2str(s(2)), 'x', ...
                num2str(s(3)), 'x', num2str(s(4))];
        else
            theSize = [num2str(D) '-D'];

I would not recommend hacking this to actually display the value of a 4-dimension variable, it would be too large to fit in the tooltip and needlessly waste memory.

For a lot of people in medical image processing where >3D matrices is the norm, it would be great to be able to see the dimension sizes rather than just the [4D] label that is assigned to such a variable. just looking for same behaviour as for dimensionality <=3. I spend a lot of time doing size(myvariable) on 4Ds and it gets a little annoying and disturbs the work flow.

In order to show a tip there has to be a variable with the same name in the workspace. You'll only see tips for variables in the current context. @Peter,

However, for some reason the datatip dose not appear anymore. Is there anybody who knows more about this... I use Matlab 7.5.0 (R2007b). The 'Enable datatips in edit mode' in the 'Preferences' is turned on. Thanks, Peter I like this feature in the debug mode. However, for some reason the datatip dose not appear anymore.

This is easily fixed on my local copy and I hope this was fixed for R2009b and R2010a. Mike,

I am not sure about your particular piece of data, but we’ve made improvements to the datatip code in R2009b and R2010a.

However, I have the following observation(bug?): In debug mode or cell mode, information about some of my structure array variables are not shown completely in the in-editor-datatip (or as output of the datatipinfo fuction call) compared to the command window when typing the variable name as shown below (it shows the structure array having 8 elements where in fact it has 188). Is this also a bug that was fixed in 2009b? Thanks! >> output output = 188x1 struct array with fields: info results >> datatipinfo(output) output: 8x1 struct array with fields: info results Hi Mike,

It is a bug, and it’s something we fixed in MATLAB R2009b.

I just started using Matlab 7.8.0 (2009a), and noticed that when I am at the bottom of my screen (and editor window), the datatips in the editor are shown below the variable I am looking at, which in this case is off the screen (I am on windows xp, on a dual-monitor situation). My memory of previous versions was that if there wasn't room to display the datatip underneath the variable it would display it above the variable. In this case, I cannot read the values (since they are below my screen), and often work at the bottom of the editor or screen, since that's where the empty space on the editor is. Is this a bug? Is there a fix? I'm sorry if this has been discussed before; I couldn't find it in the discussion forum. Thanks! ~Ben Hi Ken – I know this thread is long dead, but I have a datatips question for you.
