svd Returns Economy Decomposition
The following feature was released in MATLAB 7.0, but was undocumented until this
release.
The command svd(A,'econ') returns economy decomposition on matrices having few
rows and many columns as well as those with many rows and few columns. svd(A,0)
continues to behave as it always has, namely to only return economy-sized decomposition
on matrices having many rows and few columns.
Note that this does not carry over to the qr function as there is no valid way of cutting
out any of the information returned by qr to make an economy-sized decomposition of
matrices having few rows and many columns.
New Location for LAPACK Libraries
The location of the LAPACK libraries has been changed. These libraries are now located
in
extern/lib/win32/microsoft/libdflapack.lib
extern/lib/win32/microsoft/libmwlapack.lib
This change impacts you only if you build MEX-files that call LAPACK and BLAS
functions.
Documentation on Data Analysis
The section of the MATLAB Mathematics documentation on “Data Analysis and
Statistics” has been moved to a new MATLAB Data Analysis book. This book documents
MATLAB functions and tools that support basic data analysis, including plotting,
descriptive statistics, correlation, interpolation, filtering, and Fourier analysis. It also
documents the new object-oriented command-line API for analyzing time-series data.
