This tip displays how to add an equation with matrix, for example, the Electromagnetic tensor.

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.   On the Equation tab, in the Structures group, click the Script button:

Script button in equations Word 365

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:

  • On the Equation tab, in the Symbols group, click the More button:
    More symbols in equations Word 365
  • In the list of symbols, choose Alpha symbol in equations Word 365 and then Beta symbol in equations Word 365.

   4.   Enter =.

   5.   On the Equation tab, in the Structures group, click the Bracket button. In the Brackets list, choose round brackets:

In the Linear format:

   1.   In your own equation, enter F_.

   2.   On the Equation tab, in the Symbols group, choose Alpha symbol in equations Word 365 (or \alpha) and then Beta symbol in equations Word 365 (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/[email protected](-E_x)/c&0&-B_z&[email protected](-E_y)/c&B_z&0&[email protected](-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.
