extractmode
Band-pass filter at given frequency of a PIVMat time series

Description
MODE = extractmode(V, INDEX) extracts, using Fourier transform, 
the eigenmode, i.e. the spatial structure of a mode at a given 
frequency #INDEX, from the velocity or scalar field time series V. 
The returned field MODE is a PIVMat structure, defined as the temporal 
band-pass filter at frequency #INDEX of the input fields. The frequency 
integer INDEX is the peak number in the temporal spectrum, and can be 
obtained from the function tempspecf.
