What are some differences between arrays and matrices using the Numpy library? When would one want to use arrays instead of matrices and vice versa?

PyQwt-5.2.0 released

What is PyQwt ( http://pyqwt.sourceforge.net ) ? - it is a set of Python bindings for the Qwt C++ class library which extends the Qt framework with widgets for scientific and engineering applications. It provides a 2-dimensional plotting widget and various widgets to display and control bounded or unbounded floating point values. - it requires and extends PyQt, a set of Python bindings for Qt. - it supports the use of PyQt, Qt, Qwt, and optionally NumPy or SciPy in a GUI Python application or in an interactive Python session. - it runs on POSIX, Mac OS X and Windows platforms (practically any platform supported by Qt and Python). - it plots fast: fairly good hardware allows a rate of 100,000 points/second. (PyQwt with Qt-3 is faster than with Qt-4). - it is licensed under the GPL with an exception to allow dynamic linking with non-free releases of Qt and PyQt. The most important new features of PyQwt v5.2.0 are: - support for Qwt v5.2.0 - support for PyQt4 upto v4.5.4, PyQt3 upto v3.18.1, and SIP upto v4.8.2. - switch to documentation generated by Sphinx. - provide a normal qwt plugin for the pyuic4 user interface compiler instead of the anormal qwt plugin included in PyQt. The most important bug fixes in PyQwt-5.2.0 are: - fixed crashes in the QImage-array conversion functions. - fixed three transfer of ownership bugs. PyQwt-5.2.0 supports: 1. Python v2.6.x and v2.5.x. 2. PyQt v3.18.1 downto v3.17.5. 3 PyQt v4.5.x, v4.4.x. 4 SIP v4.8.x downto v4.7.3. 5. Qt v3.3.x. 6. Qt v4.5.x, v4.4.x, and v4.3.x. 7. Qwt v5.2.x, v5.1.x, and v5.0.x. 8. Recent versions of NumPy, numarray, and/or Numeric. Enjoy -- Gerard Vermeulen
