Hello,
I’m running MATLAB to execute a FreeFEM++ file. Currently everything is fine, except that I do not want the FreeFEM++ code to be shown in the Matlab command window. Here is an example to explain my question. I execute a FreeFEM++ file titled “FF1.edp” through the following matlab code:
_system(['FreeFem++ ',‘FF1.edp’]);_
There is only one line of code in FF1.edp file, which is as follows:
> cout \<\< “This is my FF+ file!” \<\< endl;
While in the command window of MATLAB, a lot of message appears, as shown in the following screen caption.
These messages generated from FreeFEM++ are pretty messy, especially in the case if I’m running a file with many lines of code. I wonder if there is a way to minimize the amount of these message, so that I can have a clean command window in MATLAB? Thank you.

`FreeFrem++ -v 0` should help I think. You can also redirect the output into a file.

Very neat solution, it works perfect, thank you!

and add `FreeFrem++ -v 0 -ns` to remove the dump of the script.
the list of freefem parameters
```auto
-f: [filename] script file name
-v: [verbosity] level of FreeFEM output (0 - 1000000)
-nw: no graphics
-wg: with graphics
-ne: no edp script output
-cd: change directory to script directory
-cdtmp: change directory to /tmp
-jc: just compile
-ns: same as -ne
-nowait: do not wait graphics at the end
-nc: without console (MS Windows only)
-log: with console (MS Windows only)
-wait: wait graphics at the end
-fglut: [filename] redirect graphics in file
-glut: [command] use custom glut
-gff: [command] use custom glut (with space quoting)
-check_plugin [plugin1,plugin2,...] just try if this plugins are correct
-?: show help
```

Hello I have a follow up question. I’m using [Mshdist](https://github.com/ISCDtoolbox/Mshdist) as an external package in FreeFEM++ by using the following command:
> exec(mshdist filename)
Although it works, a lot of output information appears in the command window as well. I wonder how to decrease the level of verbosity for [Mshdist](https://github.com/ISCDtoolbox/Mshdist) as well.
I know that FreeFEM++ has its own function, distance, for similar purpose with [Mshdist](https://github.com/ISCDtoolbox/Mshdist), but it seems that Mshdist is more accurate than distance in some cases.

To suppress FreeFem output, use the argument `-v 0` when calling `FreeFem++` or `FreeFem++-mpi`. You will have to look into the documentation of other packages to learn how to suppress outputs from them.
