How to insert an equation with matrix
Do the following (how to add an equation in your document, see Working with Microsoft Equation):
In the Professional format:
1. Create your own equation.
2. Under Equation Tools, on the Design tab, in the Structures group, click the Script button:
In the Script list, choose Subscript:
3. In the base box of the script, enter F, and then in the lower right box of the script:
- Under Equation Tools, on the Design tab, in the Symbols group,
click the More button:
- In the list of symbols, choose
and then
.
4. Enter =.
5. Under Equation Tools, on the Design tab, in the Structures group, click the Bracket button. In the Bracket list, choose round brackets:
6. Under Equation Tools, on the Design tab, in the Structures group, click the Matrix button. In the Matrix list choose 2x2 Empty Matrix or 3x3 Empty Matrix:
7. To increase a count of columns or/and rows of your matrix:
- right-click in it,
- in the Insert list of the popup menu, choose what and how you want to increase:
8. Enter in some positions zero, for other positions use Subscript and Fraction:
In the Linear format:
1. In your own equation, enter F_.
2. Under Equation Tools, on the Design tab,
in the Symbols group, choose (or \alpha) and then (or \beta).
3. Enter =. Then you enter a symbol equal, this linear formula transformed to the professional format:
4. In the brackets, enter the following:
(\matrix(0&E_x/c&E_y/c&E_z/c@(-E_x)/c&0&-B_z&B_y@(-E_y)/c&B_z&0&-B_x@(-E_z)/c&-B_y&B_x&0));
where \matrix is a command to create a matrix, & divides elements to columns in one row, @ divides rows in the matrix. Every time then you enter a special symbol, this linear formula transformed into a professional format.
Note: You can change spaces and alignment of your matrix, for more details see Adjusting spacing and alignment in an equation.
