Several points within this program bear mentioning: The parameters M and NDFT correspond to M and N in the above discussion. On successive calls, we recompute the Fourier transform only if a or b or h(t) has changed. Since dftint is designed to work for any value of ω satisfying ω∆
13.9 Computing Fourier Integrals Using the FFT 589 The values of M, NDFT, andMPOL are merely illustrative and should be optimized for your particular application. M is the number of subintervals, NDFT is the length of the FFT (a power of 2), and MPOL is the degree of polynomial interpolation used to obtain the desired frequency from the FFT. void dftint(float (*func)(float), float a, float b, float w, float *cosint, float *sinint) Example program illustrating how to use the routine dftcor. The user supplies an external function func that returns the quantity h(t). The routine then returns � b a cos(ωt)h(t) dt as cosint and � b a sin(ωt)h(t) dt as sinint. { void dftcor(float w, float delta, float a, float b, float endpts[], float *corre, float *corim, float *corfac); void polint(float xa[], float ya[], int n, float x, float *y, float *dy); void realft(float data[], unsigned long n, int isign); static int init=0; int j,nn; static float aold = -1.e30,bold = -1.e30,delta,(*funcold)(float); static float data[NDFT+1],endpts[9]; float c,cdft,cerr,corfac,corim,corre,en,s; float sdft,serr,*cpol,*spol,*xpol; cpol=vector(1,MPOL); spol=vector(1,MPOL); xpol=vector(1,MPOL); if (init != 1 || a != aold || b != bold || func != funcold) { Do we need to initialize, or is only ω changed? init=1; aold=a; bold=b; funcold=func; delta=(b-a)/M; Load the function values into the data array. for (j=1;j
