I got the cell names stuff with 2 field values. When I open "stuff" i see a message "1x1 struct", can i change this display to like say "1x1 NAMEIWANT"?
names = {'f1', 'f2'};
values = {1 2};
structure = struct(args{:});
stuff{1,1} = structure;
stuff{1,2} = structure;
Thanks for your time, happy holidays


"1x1 struct"
is the type of class not the name itself
ok, so how can I make something like these?

@Tiago: It is not meaningful to create a kind of table, which contains such an output for the given input. "1x1 fsrModel" is nothing, which explains the contents in a meaningful way in the data browser. This tool is designed to show the class of the variable and then "1x1 struct" is perfect. If you want to display something else, create you own uitable in a GUI, but not the standard browser for data.

In your screenshot, mlrModel, fsrModel, etc. are the name of classes. They may look like structures but these things are absolutely not structures, they're objects, instances of classes. In order to get a mlrModel you would have to call whichever function creates such objects, possibly the class constructor, with the appropriate inputs. While matlab provides a way to convert objects to structures there is no reverse operation other than what is provided explicitly by whomever wrote these classes.
In conclusion, look at the documentation of whatever library you're using to find out how to create these objects. They're not structures.


thats is just an example, because i thought that i could change 1x1 struct to 1x1 "whatever i want".
in the example i got a cell with 2 columns and it appears 1x1 structure, i would like to write for column 1 "1x1 bananas" and for column2 "1x1 pineaple" for example.
i turnarounded by transforming stuff into a table and then assign with
table = cell2table(stuff)
table.Properties.VariableNames = {'bananas','pineaple'}
Tiago, I think you need to backtrack a bit. All this display we've been talking is with the variable browser and command line display. They are designed to show you the class of whatever is stored in the cell array (unless it's a small enough matrix or char array) because that's what useful for writing and debugging code.
So, what is your use case? You seem to be using that display for other purpose. Perhaps you should be using a GUI instead as suggested by Stephen.

uitable('Data', {'Name 1', 17.3, 'fsrModel'; 'Name 2', 3.14, 'fsrModel'})

@Stephen Cobeldick the objective was just when i open "stuff" to see that the column 1 is label with a specific name and column 2 is label to another name

@Tiago: This is the section for answers. Please post comments as comments. Thanks.
Then problem is hidden in "just when I open". Opening a variable in the WorkspaceBrowser has a specific purpose. You ask for a method to create a special class just to missuse the WorkspaceBrowser to show a wanted output. This is indirect ond too complicated, because as said already it is much easier to create a new GUI instead of using the WorkspaceBrowser. Then you have the complete freedom to display what you want.
