Description

The list of methods to do cos are organized into topic(s).

Method

floatcosf(float f)
Uses Math.cos, but returns the result as a float. 
return (float) Math.cos(f);
floatcosf(float value)
cosf 
return (float) Math.cos(value);
doublecosineCoefficient(double[] hist1, double[] hist2)
cosine Coefficient 
double distance = 0;
double tmp1 = 0, tmp2 = 0;
for (int i = 0; i < hist1.length; i++) {
    distance += hist1[i] * hist2[i];
    tmp1 += hist1[i] * hist1[i];
    tmp2 += hist2[i] * hist2[i];
if (tmp1 * tmp2 > 0) {
...
floatcosineInterpolate(float y1, float y2, float mu)
cosine Interpolate 
float mu2;
mu2 = (float) (1 - Math.cos(mu * Math.PI)) / 2;
return (y1 * (1 - mu2) + y2 * mu2);
doublecosineTheorem(double d12, double d23, double theta123)
For a planar triangle 1,2,3, computes d13, based on d12,d23 and theta23 = angle(d12,d23) using the cosine theorem, i.e.: d13^2 = d12^2 + d23^2 + d12 d23 cos(theta23) 
return (d12 * d12 + d23 * d23 - 2 * d12 * d23 * Math.cos(theta123));
doublecosInt(double s)
cos Int 
return (1.0 - Math.cos(s * Math.PI)) * 0.5;
