Modules

• OA
  • vectoa(): Objective analysis for vectorial fields;
  • scaloa(): Objective analysis for scalar fields;
• DYN
  • dyn_amp(): Makes the projection of every dynamical mode to velocity to obtain its amplitude;
  • zeta(): Calculates the vorticity field by velocity field;
  • psi2uv(): Calculates the velocity field by stream function scalar field;
  • vmodes(): Calculates the QG pressure modes from N2 profile;
  • eqmodes(): Calculates the equatorial pressure and vertical velocity modes from N2 profile;
• EOF
  • eoft(): Calculates the Empirical Orthogonal Functions;
  • my_eof_interp(): Fillgaps on matrix based on EOFs (translated from Cesar Rocha Matlab version);
  • ceof(): Performs the Complex (or Hilbert) Empirical Orthogonal Functions decomposition;
  • reconstruct_ceof(): Reconstructs the CEOF modes individually;
• UTILS
  • argdistnear(): Searchs the position of the closest points in an array to a reference point;
  • meaneddy(): Performs an eddy-mean decomposition with a low-pass filter;
