A vector is a 1-dimensional array of mathematical expressions.  Use the Author > Vector command or click on the icon on the command toolbar to add a new vector to the end of the active worksheet.  After you enter the desired dimension of the vector (i.e. the number of elements), you are presented with a dialog box that allows you to type in and edit the elements of the vector (see Entering Mathematical ExpressionsEntering_Mathematical_Expressions).


When satisfied with the vector, click on the OK button or press the Enter key to add the vector to the end of the active worksheet.  Click on the Simplify button or press Alt+S to simplify the vector before adding it to the active worksheet.  Click on the Cancel button or press the Esc key to abort the command.


Alternatively, a vector can be entered by typing in an expression of the form

[x1, x2, ..., xn]

where the xi are the elements of the vector.  The elements must be separated by commas, and the vector must be delimited using square brackets, [ ], rather than parentheses, ( ), or braces, {­ }.  For example, the 3-element vector

[2·x, -5, x^2]

displays as

⎡          2⎤
⎣2·x, -5, x ⎦


To edit a vector, highlight it and issue the Edit > Object commandEE7FDI or just press the Enter key.  This command gives you the opportunity to increase or decrease the number of elements of the vector.


You can highlight the elements of vectors by clicking on them or by pressing the appropriate arrow keys (see Selecting Objects and SubexpressionsSelecting_Objects_and_Subexpressions).  For example, if a vector is highlighted, press Shift+↓ (i.e. the down arrow key) to highlight the first element of the vector.  Then press Shift+→ (i.e. the right arrow key) to highlight successive elements.
