How do create dynamic bash script for raspberry pi 4 in matlab

Hi

I have a script on raspberry pi 4 that takes three variables. These variables are generated by matlab and I need to run this script for it. The problem is that every time I try to generate this bash command, I get an error. I'm currently using Matlab Support Package for Raspberry Pi Hardware

Is it possible to do what I'm thinking? How can I do it?

Here's my trial and error returned.

Attempt 1:

 comando = convertStringsToChars(strcat(['python Desktop/R3D5/motor.py '], [' '], [ang], [' '], [dir]));
 system(raspi, comando)
 
 Error:
    Error executing command "python Desktop/R3D5/motor.py 100 1". Details:
    
    STDERR:   File "Desktop/R3D5/motor.py", line 1
    SyntaxError: Non-ASCII character '\xc3' in file Desktop/R3D5/motor.py on line 1, but no encoding declared; see
    http://python.org/dev/peps/pep-0263/ for details
    
    STDOUT:
    
    Error in R3D5_main (line 31)
    R3D5.moveBase(' 100', ' 1');
 

Attempt 2:

 
  system(raspi, 'python Desktop/R3D5/base.py '+ ang + ' ' + dir)
  Error:
    Arrays have incompatible sizes for this operation.
    
    Error in R3D5/moveBase (line 49)
                system(R3D5.r, 'python Desktop/R3D5/base.py '+ ang +' ' + dir)
    
    Error in R3D5_main (line 31)
    R3D5.moveBase('100', ' 1');

I really don't have any more ideas

Thanks in advance
