I suppose it would be possible to replace all the CRs with , or something, such as the patch I attach, but this won't work if you have ..., or other things that mess with line continuations.

Thanks for your fast answer. It's a beginning of solution.
Appending all the commands with commas is not really equivalent to fully 
hiding the commands but it helps to decouple the commands printing from 
their outputs.

Perhaps something equivalent but slightly more robust would be to embed 
the cell into a kind of multiple lines eval().

For instance, if the cell is

<code>
%% Cell 1
cmd1;
cmd2;
cmd3;

%% Cell 2
...
</code>

the Matlab shell (through the lisp file matlab.el) would have to launch

    eval(sprintf(cellstr))

where cellstr is the full string containing the text

"%% Cell 1
cmd1;
cmd2;
cmd3;"

i.e., cellstr = '%% Cell 1\n cmd1;\n cmd2;\n cmd3;\n' with perhaps some 
care for doubling the apostrophes inside.



Another point I was wondering, perhaps easier to implement, is how to 
program the "Run Cell and Advance" of Matlab,
i.e. running the current cell and make the pointer jump to the beginning 
of next cell in the editing of the script file.


I regret that I'm not sufficiently specialized in lisp to program myself 
these two features.
My emails could be interpreted simply as a wish list for your mode.
If it is too hard to implement, no problem. This mode is already very 
handy as it.

Best regards,
Laurent
