I am the happy user of matlab mode. However, for some time I have
experienced a problem/bug. When I edit a m-file and have matlab-shell
running emacs gets stuck and uses on full CPU when i pass strings
inside functions. For example the below,
y(i,:)= sum(x((1:r)+(i-1)*r,:))/r;
when the cursor pass x emacs use one full CPU until I enter ctrl-G
then the *MATLAB* buffer says
>> which xpsound
/usr/local/MATLAB/R2014a/toolbox/matlab/demos/xpsound.m
>>
if I then continue and pass r *MATLAB* says
>> which randnv
/home/tk/Matlab/MFiles/randnv.m
>>
>>
I use
>> version
ans =
8.3.0.532 (R2014a)
And also a path included above together with the m file I was
writing.
Any help is appreciated.
