EZFFT(T,U) plots the power spectrum of the signal U(T) , where T is a 'time' and U is a real signal (T can be considered as a space coordinate as well). If T is a scalar, then it is interpreted as the 'sampling time' of the signal U. If T is a vector, then it is interpreted as the 'time' itself.... Platforms: Matlab

findEulerAngs generates Euler angle sets and animates rotations in response to user manipulation of a 3D rigid body (a box).Use the mouse to change the orientation of the box. A wireframe of the original box position will appear. The 'Euler Axis' button animates the rotation about the Euler Axis... Platforms: Matlab

The fitting of smooth curve through a set of data points and extention to this is the fitting of 'best fit' spline to a large set of data points which show the cerrent trend but which do not all lie above the curve. The method involves cluster analysis, that is, grouping the crude data into... Platforms: Matlab

[coordSys,as] = animEuler(h,rotSet,angs) animates the rotation of a dextral coordinate system using three arbitrary Euler angles (angs) about three axes (rotSet) in figure (h). rotSet is an array of 3 numbers in the range of [1, 3] representing the three body axes, so that rotSet = [3,1,3] is a...
