This package includes a number of methods of determining the delay between two period signals. The delay may be calculated to subsample accuracy. Methods include: three-point interpolation using parabolic, Gaussian, or cosine functions; a phase method; and an iterative method.A simple example is... Platforms: Matlab

For purposes of these tools, a quaternion, q, is just a four element vector where q(1:3) is the "imaginary" or "vector" portion of the hypercomplex number, and q(4) is the "real" or "scalar" portion. Consequently, if q represents a rotation, then: q(1) = v1*sin(phi/2) q(2) = v2*sin(phi/2) q(3) =... Platforms: Matlab
