Hi
You need to create a layer 3 SVI (switched virtual interface) for each vlan you want to route eg.
switch(conf t)#interface vlan 223
switch(config-if) ip address "address" "subnet mask"
switch(config-if)# no shut
You might also have to enable ip routing if it isn't already on
switch(conf t)#ip routing
Attached is a link to 3750-E ip routing configuration guide for more details.
