Its pretty simple to design digital filters in matlab as opposed to languages such as C or C++ or Java. this is because matlab has its own toolboxs to design filters. you can look for a toolbox called "fdatool". Just type fdatool in the matlab command prompt, and the toolbox opens up. there is a significant amount of help in the matlab help documents on this issue too.
Its pretty simple.
