perl (MATLAB Functions)

Call Perl script using appropriate operating system executable

Syntax

perl('perlfile')
perl('perlfile',arg1,arg2,...)
result = perl(...)

Description

perl('perlfile') calls the Perl script perlfile, using the appropriate operating system Perl executable. Perl is included with MATLAB, so MATLAB users can run M-files containing the perl function.

perl('perlfile',arg1,arg2,...) calls the Perl script perlfile, using the appropriate operating system Perl executable, and passes the arguments arg1, arg2, and so on, to perlfile.

result = perl(...) returns the results of attempted Perl call to result.

Examples

Given the Perl script, hello.pl

$input = $ARGV[0]; 
print "Hello $input.";

run the following statement in MATLAB

```
perl('hello.pl','World')
```

MATLAB returns

```
ans =
Hello World.
```

It is sometimes beneficial to use Perl scripts instead of MATLAB code. The perl function allows you to run those scripts from within MATLAB. Specific examples where you might choose to use a Perl script include

Perl script already exists
Perl script preprocesses data quickly, formatting it in a way more easily read by MATLAB
Perl has features not supported by MATLAB
