How to connect an Arduino to Matlab run on a Mac? Error using serial/fopen (line 72)

I downloaded Arduino software, established Arduino connection to Arduino software, but I'm unable to connect the Arduino with Matlab.

Input:

s = serial('/dev/tty.usbmodem1411')

Output:

Communication Settings

Port: /dev/tty.usbmodem1411

BaudRate: 9600

Terminator: 'LF'

Communication State

Status: closed

RecordStatus: off

Read/Write State

TransferStatus: idle

BytesAvailable: 0

ValuesReceived: 0

ValuesSent: 0

Input:

set(s,'DataBits',8); set(s,'StopBits',1); set(s,'BaudRate',9600); set(s,'Parity','none'); fopen(s);

Output: error using serial/fopen(line 72) Open failed: cannot connect to the /dev/tty.usbmodem1411 port. Possible reasons are another application is connected to the port or the port does not exist.
