title: i need to implement a Butterworth filter in C. Is it easier get a library with this functionality or write the code?
body: <p>My project is in C, CodeBlocks is my IDE and i´m running on windows Vista. I need to apply a Butterworth Filter to my data. I could do this automatically with Matlab as it had this (and other) Filter as a built in function. Computers and programming aren´t exactly my area and i have never "imported" a new library, and dont know how to do this. Is it complicated? and what would it be best I do? write the code for the Butterworth Filter as a function? or "import" a library to do this for me? (personally, if isnt that complicated, i´de prefer to get a library because it would probably have other types of filters i could also test)</p>
