This Function HistConnect will make a smooth histogram for a signal or image consisting of a few samples. The function assumes correlation between the samples, and implicitly generates new linear-interpolated samples between the originate samples. Thus makes the assumption of continuity between...

The samples of code included numerically solve the diffusion equation as it arises in medical imaging. This process is done with multiple solution methods, various boundary conditions, and in multiple dimensions.

A Lambert-orbital boundary value problem can be stated as"Find the orbit/trajectory of a spacecraft that flies from position [r1] to [r2], taking a time [tf] and making [m] complete orbits before arriving at [r2]. "The solution to each Lambert-problem is NOT unique; one can travel to [r2] via the...

The code implements the shooting method by means of the Runge-Kutta method of 4th order and the interval bisection method. There is the graphical interface too. When the differential equation is inserted in terms of the standard mathematical notation (no in MATLAB code), the programme create the...
