How Do I
Enter a Matrix?
Entering matrices in Maple is very simple. This section demonstrates two methods for entering a matrix: by inserting a template from the Matrix palette and by using the Matrix-constructor shortcut syntax.
Before you proceed, be sure to familiarize yourself with entering simple mathematical expressions . Open a new worksheet in Document mode, and ensure that you are in Math mode.

Follow the steps below to enter the three-by-four matrix 12364561578924 and assign it to a variable whose name is M.
Step
Description
Illustration
1
Type M, followed by a colon (:) and an equal sign (=). The colon-equals notation assigns the content on the right-hand side to a variable on the left-hand side.
2
In the Matrix palette, either:
Click and hold the Choose... button and drag a three-by-four rectangle in the box that pops up, or
Type 3 into the Rows field and 4 into the Columns field.
3
Click Insert Matrix.
4
Type 1 over the highlighted placeholder. To move to and highlight the next placeholder, press the Tabkey.
5
Continue to navigate through the placeholders by pressing Tab to enter values for the entire matrix.
6
Press Enter. Maple displays and labels the result of an executed statement in a new line. (For more information, see the How do I topic on evaluating expressions and the Equation Labels subsection of the How Do I help page under the Tools and Features heading.)
When Working with Templates From the Palettes, Keep These Tips in Mind:
If you accidentally move the cursor outside a template, simply move the cursor back into the template and press [Tab] to move to the next placeholder.
Use Shift + Tab to move back to the previous placeholder, if you have not overwritten it yet.
To add a row to a template, place the cursor in an element and from the Context Panel, select Insert Row. Alternatively, press Ctrl+Shift+R.
To add a column to a template, place the cursor in an element and from the Context Panel, select Insert Column. Alternatively, press Ctrl+Shift+C.
Follow the steps below to enter the three-by-four matrix 12364561578924 and assign it to a variable whose name is M. For details about the special syntax used in these steps, see the associated help topic .
Type M, followed by a colon (:) and an equal sign (=). The colon-equals notation assigns the content on the right-hand side to a variable name on the left-hand side.
Type two left angle brackets (<) (<), followed by 1,4,7 (separated by commas), and a right angle bracket (>). The expression 1,4,7 represents the first column of the final matrix.
Press Shift + | to type the pipe character (|). This character separates the four columns in the final matrix.
As before, type the columns 2,5,8, 3,6,9, and 6,15,24, separated by pipe characters (|). Type a final right angle bracket (>). The angular brackets are automatically formatted by Maple.
Press Enter. Maple displays and labels the result of an executed statement in a new line. (For more information, see the How do I topic on evaluating expressions and the Equation Labels subsection of the How Do I help page.)
When Working with this Shortcut Syntax, Keep These Tips in Mind:
The comma (,) is used to separate elements in different rows, while the pipe symbol (|) is used to separate elements in different columns.
As a result, the matrix could also be entered as 1|2|3|6,4|5|6|15,7|8|9|24.
The methods described in this help page provide simple ways to enter matrices with a small number of entries. For more ways to enter a Matrix, including using an initializer or importing data, see How to Construct Matrices in Maple .
