>> index_emd
index_emd.M list of functions in the EMD package
type help function_name for more information on a specific function
Empirical Mode Decomposition
emd - computes EMD and bivariate/complex EMD with various options
emd_local - computes local EMD variation
emd_online - computes on-line EMD variation. Note that it does not truly
apply on-line: the function is only a demonstration.
emdc - fast implementation for EMD with Cauchy-like stopping criterion
(requires compilation, see make_emdc function)
emdc_fix - fast implementation for EMD with predefined number of iterations
(requires compilation, see make_emdc function)
cemdc - fast implementation for bivariate/complex EMD (first algorithm)
with Cauchy-like stopping criterion (requires compilation,
see make_emdc function)
cemdc_fix - fast implementation for bivariate/complex EMD (first algorithm)
with predefined number of iterations (requires compilation,
see make_emdc function)
cemdc2 - fast implementation for bivariate/complex EMD (second algorithm)
with Cauchy-like stopping criterion (requires compilation,
see make_emdc function)
cemdc2_fix - fast implementation for bivariate/complex EMD (second algorithm)
with predefined number of iterations (requires compilation,
see make_emdc function)
Utilities
install_emd - setup Matlab's path and compile the C codes.
uninstall_emd - revert the modifications made by install_emd and remove the
files (optional).
make_emdc - compile all C codes
emd_visu - visualization of EMD
cemd_visu - visualization of bivariate/complex EMD (automatically called
by emd_visu when the input is complex)
cenvelope - compute envelope curves for bivariate/complex EMD
cemd_disp - visualization of envelope curves and tube envelope
plot3c - plot a complex vector in 3 dimensions
plotc - plot the projection of a complex vector on a variable direction
dirstretch - directional stretching of a complex vector
hhspectrum - compute Hilbert-Huang spectrum (need the Time-Frequency Toolbox
http://tftb.nongnu.org)
toimage - transform a spectrum made of 1D functions (e.g., output of
"hhspectrum") in an 2D image
disp_hhs - display the image output of "toimage" as a Hilbert-Huang spectrum
addtag - add a tag to a graphic object (uses the Tag property as a list
of keywords or "tags")
rmtag - remove a tag from a graphic object (uses the Tag property as
a list of keywords or "tags")
hastag - test whether a graphic object has a specific tag (uses the Tag
property as a list of keywords or "tags")
findtag - find objects having a specific tag (uses the Tag property as
a list of keywords or "tags")

emd_fmsin - Fig. 1: a 3-component example (need the Time-Frequency
Toolbox http://tftb.nongnu.org)
emd_triang - Fig. 2: another 3-component example
emd_sampling - Fig. 3: effect of sampling on 1 tone
emd_separation - Fig. 4: separation of 2 tones
ex_online - Sect 3.4: the way emd_online.m works
triangular_signal - subroutine called by emd_triang (formerly triang.m)

"Bivariate Empirical Mode Decomposition",
Signal Processing Letters (submitted)
bivariate_EMD_principle - Fig. 1: principle of the bivariate/complex EMD
bivariate_EMD_mean_definitions - Fig. 2: definition of the mean for each algorithm.
Also allows to test other signals and parameter sets.

on an oceanographic float position record
