MATLAB: Increase Datatip display precision (2014b)

datatipMATLABprecision

It appears that Mathworks has changed the internal architecture of MATLAB sufficiently such that the old method of increasing the Datatip displayed precision (via editing default_getDatatipText.m) is no longer possible. The file and directories no longer exist.

Has anyone been able to accomplish the same result in the new software (2014b, for example)?

Thank you,

Can you use the UpdateFcn of the datacursormode

function txt = myupdatefcn(obj, event_obj)
pos = event_obj.Position;
txt = {sprintf('X: %.16g', pos(1)), sprintf('Y: %.16g', pos(2))};

MATLAB: Cellfun, too many output arguments (2014b)

That first call attempts to call the disp function with 0 input arguments and 1 output argument, then pass the output argument from that disp call into cellfun as its first input argument. The disp function can have a maximum of 0 output arguments [it doesn't return anything.]

The second call creates an anonymous function and passes that into cellfun. When cellfun calls that anonymous function, since the cellfun call has 0 output arguments so does the anonymous function call. Because the anonymous function is called with 0 output arguments, so is disp.

You can simplify that second call a little bit by using a normal function handle.

cellfun(@disp, {'how', 'are', 'you', '?'})

MATLAB: Passing variables into custom datacursor in a GUI

set(dcm, 'update', {@display_datacursor, step});

with

function output_txt = display_datacursor(obj, event_obj, step)

and do not assign to step in the function.
