Help Needed

I'm siva doing my final year of engineering in a reputed college in south India. I'm doing my final year project using Scilab and since i don't have any idea of how to work in scilab i ask for this help. I'm supposed to design a FIR filter and integrate it with a server scheduler. I seriously don't know how I am going to do this yet I have the time and support to finish it. So I kindly request fellow members to help me out with initially designing a FIR filter in Scilab.

Thanks in advance.
