execute Linux script with expect

Matlab R2015a

Hello,

In order to programmatically ssh connect I made an expect script as explained in

https://stackoverflow.com/questions/45129323/ssh-connect-and-commands-programmatically

#!/usr/bin/expect
set login "any_user"
set addr "some_address"
set pw "any_pwd"

spawn ssh -t $login@$addr
expect "$login@$addr\'s password:"
send "$pw\r"
expect "~" ; # put here string from your server prompt
send "mkdir some_dir\r"
interact

I called this script LoginSSH.sh (of course, with my own data), then I run this command in the Linux console without problems:

./LoginSSH.sh

The idea was to run this command from Matlab with system():

scmd='./LoginSSH.sh'

[status,cmdout]=system(scmd)

But for some reason Matlab has some problems to execute the script via system(). This is the output:

    status =

         1  

    cmdout = 

OpenSSL version mismatch. Built against 100020af, you have 1000107f

send: spawn id exp4 not open
    while executing
"send "$pw\r""
    (file "./LoginSSH.sh" line 8)

I can even run the command in Python:

import os
from subprocess import call
call(["./LoginSSH.sh"])

again, without any problems.

What could be the reason Matlab won't like to run the shell script?

Thanks in advance.
