Compatibility Issues in Maple 14
The following is a brief description of the compatibility issues that affect users upgrading from Maple 13 to Maple 14.
Converting to Nested Lists
Drawing Graphs in 3-D
Exporting Matrices to MATLAB® Format
Extracting Floating Point Numbers from Arrays
Changes within the Statistics Package
The default value for the numpoints option has changed from 49 to 200. For the majority of 2-D plots created with the default settings of the adaptive option, this change should not have any significant effects on performance or the look of the output. If you wish to use the old numpoints setting, you can override the default by issuing the command plots[setoptions](numpoints=49) before calling the plot command. Similarly, the default value for the resolution option has changed from 200 to 800. For more information on plot options, see plot/options.
Error checking has been strengthened for various commands in the plots package accepting point data as input. As a consequence, certain calls which previously produced a result but were incompatible with the documented calling sequence now produce an error message.
The convert/list command now accepts a nested option. This replaces the convert/listlist command, which has been deprecated. For more information on converting rtables, tables, or other data structures into nested lists, see convert/list.
The plots[graphplot3d] command has been deprecated. Use the command GraphTheory[DrawGraph] with the option style=spring instead.
The ExportMatrix command exports to the latest MATLAB® version supported by Maple. Calling ExportMatrix with the target=Matlab option will generate a MATLAB® Version 7 binary file. You can use the mode option to generate a Version 6 binary file that does not use data compression or an ASCII file, the default output in earlier versions of Maple.
Prior to Maple 14, extracting an element from Arrays with datatype = float returned a floating-point number using Maple's software float representation. Now, extracting a single element from a datatype=float array will return the number using Maple's HFloat representation. No base 2 to base 10 exponent change is incurred. See Numerics Updates in Maple 14 for more information.
The definition of the Von Mises distribution has changed. The probability density is now symmetric about its parameter a. This definition lends itself better to computation. For more information about the distribution, see Statistics[Distribution][VonMises].
The Statistics commands BarChart, ColumnGraph, BoxPlot, and PieChart used to accept an option named captions. This option was frequently confused with the general plot option named caption. To avoid this confusion, the captions option has been renamed datasetlabels. The commands do still accept the old option name, captions.
