Hello guys, i have installed the Raspberry pi package support for matlab but when i give the command:
mypi = raspi
i obtain this error:
Error using raspi (line 160)
Cannot establish an SSH connection to the board with device address "192.168.1.2".
Caused by:
Error using raspi (line 156)
Error executing command: FATAL ERROR: Network error: Connection refused
During the installation of the package i have set a static ip for the raspberry in this way:
IPv4 Address. . . . . . . . . . . : 192.168.1.2
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1
And, if is important for the resolution of my problem, i have connected the raspberry pi to my pc with a ethernet cable, and the pc is connects to internet with a usb key wireless. The router is not phisically connected to the pc.

There is no SSH server running on 192.168.1.2 and the target machine is refusing SSH connection request from MATLAB.
1. Login to your Raspberry Pi using a monitor and keyboard and check that the board has the correct IP address. After logging in to Raspberrry Pi, execute the following in a Linux shell window
$ ifconfig eth0
Verify that the "inet addr" displayed as a result of the command above is "192.168.1.2". If not, you need to modify your /etc/network/interfaces file to assign a static IP address.
2. SSH server is running:
$ps -ef | grep sshd
This should return an sshd server running on your Raspberry Pi if you do not see anything reboot your Raspberry Pi
3. Ping your Raspberry Pi from within MATLAB:
>> ! ping 192.168.1.2
This should be successful.
Report what you are getting.
