Lines Matching full:cosine

27  * As most of our functions use sine or cosine at equal steps,
32  * to calculate sine(wstart + n * wstep) or cosine(wstart + n * wstep)
37  * or looking at just the imaginary sine term, as the cosine follows identically:
44  * cosine generation due to the complex * complex multiply (full rotation).
52     SineGen(double wstart, double wstep, bool cosine = false) {
53         if (cosine) {
83     double mCurrent; // current value of sine/cosine
84     double mPrevious; // previous value of sine/cosine
101     SineGenGen(double outerStart, double outerStep, double innerStep, bool cosine = false)
102             : mSineInnerCur(outerStart, outerStep, cosine),  in mSineInnerCur()  argument
103               mSineInnerPrev(outerStart-innerStep, outerStep, cosine)  in mSineInnerCur()
440      * using cosine generation/multiplication, thereby saving one multiply per inner loop.
445      * We use the basic recursion to incorporate the cosine steps into real sequence x[n]:
468     SineGen cc((start - L) * w, w, true); // cosine
469     SineGen cp(start * w, w, true); // cosine
