Opens a variable in the Variables Editor (grabs focus if already open) and scrolls to given position/subs.
Supported scrollable classes (matrices):
* numeric
* logical
* cell
* timeseries
* table (from R2013b - v2.1)
* categorical (from 2013b - v2.1)
* dataset (Statistics Toolbox)


% Scroll a simple logical variable
a = false(1e6,100);
pos = randi(1e8,1);

% Scroll somewhere else
scrollto('a',[1e5, 28])

% Wrap into a structure and scroll the indexed variable = a;

% Wrap into cell and scroll with several levels of nesting
c = {s};
scrollto('c{1}.foo', pos)

% Scroll 3D array
a = rand(10,10,10);

WARNING: this code heavily relies on undocumented and unsupported Matlab functionality.

This is very useful. I have found one repeatable error, at least when using tables. On first use, whether the variable is already in VE or not, the right row is highlighted but the row is not generally visible. The table is scrolled to somewhere further down the table. With a large row number, the error can be quite large. Simply reissuing the command makes the right row visible, and all subsequent calls do likewise. So, there appears to be some minor initialization issue. The workaround (issuing the first command twice) is simple and effective. Just thought it might be a useful heads up to the developer (to whom, many thanks for this useful solution to a noxious problem).

@Klaus: the code is hosted on github and you can raise an issue there outlining the feature request and suggesting a solution, or you can submit a pull request directly with your changes!

I have found a basic implementation for scrolling struct arrays which works well for me. Pls. contact me if you need further details.

Very useful indeed.
Unfortunately struct arrays do not seem to be scrollable in M2013b.
What would be the way to implement this?



Edited description

Linked to github

Added support for table and categorical arrays (classes introduced with R2013b)

Edited description.

Additional feature:
- scrolls from 'caller' ws, e.g. scroll in debug mode;

Fixed bugs:
- now handles corner case within size-bounds scrolling;
- corrected the scrolling type of ts to dataset (was swapped before).
