How to implement Matlab fir1 function in C?

    Hi all,

    In Matlab, we use fir1 function to calculate fir filter coefficients.
    For example,

    fir1(10,0.375)

    Outputs are:
    ans =

    Columns 1 through 10

    -0.0019 -0.0133 -0.0161 0.0766 0.2677 0.3742
    0.2677 0.0766 -0.0161 -0.0133

    Column 11

    -0.0019

    I wonder how it works and how to implement the fir1(n, wn) function in
    C programming language.
    Thanks a lot!
    Please help!

    Jedora.

    You probably want to start in a newsgroup that discusses the fir
    algorithm. After you try to implement it, you can come back here with
    your code and ask questions.

    Hi Jedora,

    Were you able to find out the algorithm for Fir1 .. Let me know incase
    you done it.

    regards,
