How to insert an equation with matrix

This tip display how to insert an equation for example, the Electromagnetic tensor.

Do the following (how to add an equation in your document, see Working with Microsoft Equation):

In the Professional present:

    1.    Create your own equation.

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

In the Script list choose Subscript:

    3.    In the base box of script enter F and in the lower right box of script:

  • On the Equation Tools Design tab, in the Symbols group, click the More button:
    More symbols in Word 2013
  • In the list of symbols choose Alpha and then Beta.

    4.    Enter =.

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

In the Linear present:

    1.    In your own equation enter F_.

    2.    On the Equation Tools Design tab, in the Symbols group, choose Alpha (or \alpha) and then Beta (or \beta).

    3.    Enter =. Then you enter an equal symbol, 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 special symbol, this linear formula transformed to the professional format.

Note: You can change spaces and alignment of your matrix, for more details see Adjusting spacing and alignment in an equation.
