What is spectral decomposition?
Spectral Decomposition or time-frequency analysis (also time-frequency decomposition) is a method employed to aid in the interpretation of seismic data. Spectral decomposition can be performed on a multitude of attributes (frequency, dip, azimuth…), though the frequency is the most common.
How do you decompose a matrix in Matlab?
dA = decomposition( A ) returns a decomposition of matrix A that you can use to solve linear systems more efficiently. The decomposition type is automatically chosen based on the properties of the input matrix. dA = decomposition( A , type ) specifies the type of decomposition to perform.
