[Matlab-emacs-discuss] Run-Region Problem

[Elliot J. B. <ell...@fd...>]

I'm having trouble running a block of code that makes calls to a function  
that saves data to and then loads it from an external file. For example, I  
have written the function 'my_func':

function R = my_func(n)

     [r,v]=system('echo -n $PPID');
     idx = regexp(v, '\^\[$');
     if ~isempty(idx)
         v = v(1:idx-1);
     end

     filename = ['/tmp/my_func_file_' v '.mat'];
     save(filename, 'n');
     n = load(filename);
     system(sprintf('rm %s', filename));

     R = n;

I then call my_func multiple times from test.m:

my_func(3)
my_func(4)
my_func(5)

If I run test.m using 'Save and Go', it works fine. But if I highlight the  
three calls to my_func and run them using 'Run Region' I get the following:

>> my_func(3)
/bin/bash: -c: line 0: syntax error near unexpected token `('
my_func(4)
my_func(5)
/bin/bash: -c: line 0: `rm /tmp/my_func_file_11093my_func(4)'

ans =

     n: 3

>> my_func(4)
/bin/bash: -c: line 0: syntax error near unexpected token `('
my_func(5)
/bin/bash: -c: line 0: `rm /tmp/my_func_file_11093my_func(5)'

ans =

     n: 4

>> my_func(5)

ans =

     n: 5


Any suggestions how to solve this?

Thanks.

Hi,

I'm not sure.  I tried some experiments, and things seemed okto me running on Linux.

You should probably dbstop in my_func, and then see what kind of command it is generating when you use run region to see if there is some sort of line ending problem.
