%  Release Notes Partial Differential Equation Toolbox Version 1.0.3
%
%  PDE Toolbox version 1.0.3 is a point release of the PDE Toolbox.
%  It includes several bug fixes to version 1.0.2.  It's functionality
%  is essentially the same.
%
%  Printing note:
%
%  On Windows machines, pdetool does not use the standard print dialog.
%  Instead it uses a crossplatform print dialog, where device drivers
%  other than the standard Windows print driver can be specified.  This
%  is useful for printing solutions to a Postscript printer, using the
%  -dps option, so interpolated colors/grays will be printed.  In
%  order to use these alternate drivers, the port LPT1: must be captured
%  to the printer.  Instructions for capturing a port are
%  available on the WWW at
%
%  http://www.mathworks.com/support/solutions/v4/6730.html
%
%  Bug fixes:
%
%  1) Outline of ellipse during rotation has been fixed.
%
%  Documentation bugs (for pre-May 1997 printings):
%
%  1) On page 2-10, line 9 of the example code should read:
%        u=pdenonlin(b,p,e,t,c,0,0,'Tol',rtol);
%
%  Known issues and bugs:
%
%  1) Some geometries, notably multiple concentric circles, may not be
%     represented correctly in draw mode, producing an error.  The
%     only work around at this time is to quit PDEtool and restart it.
%     A fix for this problem is currently being developed for the next
%     release.

% OLD VERSION RELEASE NOTES:
%
%  Release Notes Partial Differential Equation Toolbox Version 1.0.2
%
%  PDE Toolbox version 1.0.2 is a point release of the PDE Toolbox.
%  It includes several bug fixes to version 1.0.1.  It's functionality
%  is essentially the same.
%
%  Printing note:
%
%  On Windows machines, pdetool does not use the standard print dialog.
%  Instead it uses a crossplatform print dialog, where device drivers
%  other than the standard Windows print driver can be specified.  This
%  is useful for printing solutions to a Postscript printer, using the
%  -dps option, so interpolated colors/grays will be printed.  In
%  order to use these alternate drivers, the port LPT1: must be captured
%  to the printer.  Instructions for capturing a port are
%  available on the WWW at
%
%  http://www.mathworks.com/support/solutions/v4/6730.html
%
%  Bug fixes:
%
%  1) In version 1.0.1, when drawing mode was left, and then reentered,
%     the position of the shapes could not be altered. This has been
%     corrected.
%
%  2) In previous versions, the mechanical shear stress was miscalulated
%     by 30%.  This has been corrected.
%
%  3) Some 3-D plots previously did not plot correctly; this has been
%     corrected.
%
%  4) Incorrect scaling on some plots has been fixed.
%
%  Documentation bugs (for pre-May 1997 printings):
%
%  1) On page 2-8, line 6 of the example code should read:
%        ur=real(exp(-j*2*pi/10*sqrt(-1))*u);
%
%  2) On page 2-10, line 9 of the example code should read:
%        u=pdenonlin(b,p,e,t,c,0,0,'Tol',rtol);
%
%  3) On page 2-37, last line, the command "Specify PDE" has become
%     "PDE Specification."
%
%  Known issues and bugs:
%
%  1) Some geometries, notably multiple concentric circles, may not be
%     represented correctly in draw mode, producing an error.  The
%     only work around at this time is to quit PDEtool and restart it.
%     A fix for this problem is currently being developed for the next
%     release.

%
% Release Notes Partial Differential Equation Toolbox Version 1.0.1
%
% PDE Toolbox version 1.0.1 is a Matlab 5 compliant version of PDE Toolbox
% version 1.0. The functionality is similar to PDE Toolbox version 1.0 with
% the following exceptions:
%
% 1) Due to changes in the Handle Graphics object properties, Model M-files
%    generated using PDE Toolbox 1.0 and Matlab 4.2c will not work with PDE
%    Toolbox 1.0.1 and Matlab 5. PDE Toolbox 1.0.1 contains a model conversion
%    function, pdemdlcv.m, that converts old Model M-files for use with
%    PDE Toolbox 1.0.1 and Matlab 5. Conversely, Model M-files generated using
%    PDE Toolbox 1.0.1 will not work using PDE Toolbox 1.0 and Matlab 4.
%
% 2) Several minor bugs have been corrected.
%
% Additions to the documentation
%
% 1) Entry on initmesh, page 5-37: The property name/property value pair
%    Hgrad with a numeric value (default 1.3) has been added. The parameter
%    describes the growth rate of the mesh size away from a small part of
%    the geometry. Valid property values are between 1 and 2.
%
% 2) Entry on the Mesh Parameters dialog box, page 3-22: Hgrad (see above)
%    has been added to the dialog box. Valid entries are values between 1
%    and 2.
%
% 3) Entry on the PDE Coefficients dialog box, page 3-18: Addition to the
%    last paragraph: c can be entered using one, two, three, or four
%    values, separated by spaces. Each value represents one row in c. See
%    the entry on assempde in the "Reference" chapter for a detailed
%    description of the representation of the PDE coefficients.
%
% 4) The parameters epsilon in the Electrostatics application mode, sigma
%    in the Conductive Media DC application mode, k in the Heat Transfer
%    application mode, and D in the Diffusion application mode can be
%    entered using one, two, three, or four values, separated by spaces,
%    i.e., it is possible to model orthotropic and anisotropic
%    coefficients. For the other nongeneric application modes, isotropic
%    coefficients (one value) must be used.
%
% 5) In the AC power electromagnetics application mode, page 2-51 in the
%    PDE Toolbox User's Guide, the resistive heating rate, should be
%    Q=E^2*sigma (and not Q=E^2/sigma). The correct value is now computed
%    by the toolbox.
%
%
% List of known bugs or potentially inconsistent behavior
%
% 1) Object labels and selection indication "frames" in Draw mode and PDE
%    mode may disappear after zooming.
%
% 2) For the Generic System application mode in pdetool, the c
%    coefficient must be entered with the same structure for all subdomains.
%
% 3) You can obtain information about triangle and node numbers (Mesh mode)
%    or the plotted property (Plot mode) by positioning the cursor and
%    pressing a mouse button. The information is displayed on the
%    information line as long as the mouse button is depressed. For large
%    problems (many nodes) it may take a while for the information to
%    appear.
%
% 4) It is good practice to press the Return key after having filled out
%    any white edit field in the graphical interface. This executes the
%    callback to the edit control. Otherwise you may have to click twice on
%    any action push button to make it react. This is because the first
%    click executes the callback to the edit control.
%
%
%  Problems that occur on the Microsoft Windows platform only
%
% 5) Icon buttons in the toolbar may not appear depressed even after
%    pressing them. However, the corresponding function is always invoked.
%
% 6) The clipping of objects does not always work properly when the
%    dimensions of the drawn objects exceed the current axes limits.
%
%
% Problems that occur on the UNIX platforms only with black and white monitors
%
% 7) The PDE Toolbox is not supported on these platforms.
