C Programming Language :: How to implement Matlab fir1 function in C?


	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. Remove del for email Hi Jedora, Were you able to find out the algorithm for Fir1 .. Let me know incase you done it. regards, Shanu On 5 30 , 6 46 , wwwku@gmail.com wrote: > Hi Jedora, > Were you able to find out the algorithm for Fir1 ..
