question for filter implementation | Matlab DSP

Technical discussion about Matlab and issues related to Digital Signal Processing.

hi guys, This is nasim, i am working as a DSP engg. in chennai ( india ). My work is to convert many matlab functions in C. just like linkage, cluster and to implement filter in C. Here, i am facing a problem in implementation filter. basically i am not able to convert the "filtfilt" function in C. bcos of "filter" function that is used in "filtfilt'. In matlab filter is being designed with initial condition. i got problem in designing the filter with initial condition. i am using chebyshev1 low pass filter with 300hz and fs=4000, 4th order. initial condition r 4 constant values. unfortunately i cant go in to filter function. In addition i also got problem in implementation of banpass filter in C. bcos matlab is giving 9 coefficient for bandpass filter . so how to implement bandpass filter in C directly from 9 coefficient of matllab. plz help me with right information. regards nasim note: waiting for reply
