Piecewise Parabolic Interpolation
It performs piecewise parabolic interpolation and approximated calculation of first and second derivative at the interpolation point. Requirements: · MATLAB 5.2 or higher ...
Moivre
This formula will calculate the roots of a multidimensional array of complex numbers. Requirements: · MATLAB 7 or higher ...
Sea surface
It uses the Pierson-Moskowitz spectrum for the frequency/wave-number dependency and four different types of angular spreading like cosinus-squared, Mitsuyasu, Hasselmann and none. Requirements: · MATLAB 7 or higher ...
Sea elevation
It needs as an input the value for wind speed to generate a stochastic sea-surface one-dimensional realization.It uses the Pierson-Moskowitz spectrum. Requirements: · MATLAB 7 or higher ...
tree network
The package includes various examples with networks with 12 and up to 300 nodes. Requirements: · MATLAB 7.6 or higher · CPU and memory requirements strongly dependent on network size ...
SAT ORBIT
The routine parses a TLE file and extracts informations from a selected satellite. It then calls the SGP4 propagator, converts the orbit in the ECI reference into Earth Centered Earth Fixed and also into Lat Long Heigth. This subroutine includes an example of the ENVISAT satellite in which the accuracy of ...
REPLICATE
The script currently supports 2D & 3D arrays. Requirements: · MATLAB 7.5 or higher ...
Findsubmat
The function looks and returns the linear index of the location where the first element of matrix B is within matrix A. Requirements: · MATLAB 7.4 or higher Limitations: · Only works for 2-d matrices or vectors, both of which may contain NaNs or Infs. ...
