1/6/2024 0 Comments Mathematica clearThe latter problem uses the "event detection" feature of MATHEMATICA, which remains unchanged in the new version. PSC, Problems 2 & 16: If you append a solution to Problem 16 to your solution of Problem 2, you will be awarded extra credit.In fact, you can continue to use the old command by loading the package with the command xval Alternatively, you may use the new command StreamPlot. Chapter 6 and PSB: The command VectorFieldPlot in the package VectorFieldPlots has been superseded by the built-in command VectorPlot.If I may quote from the help on the command N, "Unless numbers in 'expr' are exact, or of sufficiently high precision, N may not be able to give results with n-digit precision." An example may be found in Chapter 4.You can always reset the kernel by following the instructions in Section 4.2.1, p. The Mathematica commands in this tutorial are all written in bold black. The command Clear will definitely clear everything, but you should use that command cautiously. As a friendly reminder, dont forget to clear variables in use and/or the kernel. It is best to clear the specific variables that you want cleared, e.g., Clear. Refer to the Mathematica documentation for. Chapter3, Section 3.10: The implication is that the command Clear will clear all variables and definitions. In the following subsections, Ill review the most im- portant attributes.clearvars -except keepVariables removes all variables, except for those specified by keepVariables. If any of the variables are global, clearvars removes these variables from the current workspace only, leaving them accessible to any functions that declare them as global. In general, you should pay close attention to these messages when they appear they usually, although not always, contain useful information. clearvars variables removes the variables specified by variables. Sometimes commands that previously elicited warning messages no longer do for example, sol4 on p. For example, try the command on line "In" on p. Chapter 3: You will find that the syntax of some error and warning messages has changed.In Problem 12 of PSA, you're asked to access the "sum" symbol from that palette. 8: The BasicMathInput palette is now called the Basic Math Assistant. The philosophy is that you spend less time reading manuals like DEwM and more time experimenting on your own to learn the software system. You can now enter commands like DSolve, not only by typing them in the Command Window, but alternatively by clicking on a palette element. More importantly, in addition to beefing up the symbols and operations that are available, MATHEMATICA now has inside the Basic Math Assistant palette, a roster of Basic Commands. It is also worth pointing out that the most important change in the newest version (i.e., 8) is the much more robust palettes that are available. In particular, if you discover any other changes or problems with the software that are not accounted for in the list below, please bring them to Dr. Additional entries will be made if/as new discrepancies are uncovered. In the roster below is a description of relevant changes, arranged more or less in the order in which you will encounter them as you progress through the course. Fortunately, there have not been many changes in the software that affect the commands and code relevant to this ode course. You are almost certainly using a more current version - possibly 7 and more likely 8. Versions of MATHEMATICA DEwM was written when the current version of MATHEMATICA was 6.

Press Command + Shift + G to open a file search dialog and enter “~/Library/Mathematica/”. To navigate to a hidden folder, open the Finder application. These folders may be hidden on your computer. Mathematica will recreate these directories the next time you start the software.
