V_HOSTIPINFO get host name and internet connection information
Usage: hostname = v_hostipinfo; % computer name
ip_address = v_hostipinfo('i'); % IP address
Inputs: m mode input selects the information to output (see below)
t optional output from an "ipconfig -all" command
Outputs: ipinfo cell array with one row per IP connection. The number
of columns is detemined by the m input (see below).
If only a single output value is selected by the m input, then
ipinfo will be a string rather than a cell array.
tt output from the "ipconfig -all" command
The "m" input selects whch IP connections to supply information about
(rows of IPINFO) and what information to supply (columns of IPINFO).
Row selection: A include all connections
L Local Internet Connection [default if m non-empty]
B Bluetooth Connection
P PPP connection (e.g. a VPn connection)
Col selection: h hostname (same for all connections) [default if m is empty]
c Connection type code: L=local, B=bluetooth, P=PPP or ?=other
t Connection type (e.g. "Ethernet" or "PPP")
n Connection name (e.g. "Local Area Connection")
m MAC address (e.g. "00-53-45-00-00-00"
i IP address (e.g. "192.168.1.1") [default if m non-empty]0001 function [ipinfo,tt]=v_hostipinfo(m,t) 0002 %V_HOSTIPINFO get host name and internet connection information 0003 % Usage: hostname = v_hostipinfo; % computer name 0004 % ip_address = v_hostipinfo('i'); % IP address 0005 % 0006 % Inputs: m mode input selects the information to output (see below) 0007 % t optional output from an "ipconfig -all" command 0008 % 0009 % Outputs: ipinfo cell array with one row per IP connection.
