Matrix Parameters

For questions using matrix mode, the parameters listed in this table are used to set the type and size of the matrix, as well as provide label and expandable/static options.

Parameter	Description	Required?	Values
matrix_mode	Turns an answer blank into a matrix mode blank, setting the visual display. Used instead of an <_> answer blank. By default, the matrix is expandable.	Yes	Values can be set to one of the following: `matrix_mode='matrix'` creates a matrix with expandable rows and columns `matrix_mode='columnvectors'` creates a matrix with expandable columns `matrix_mode='rowvectors'` creates a matrix with expandable rows `matrix_mode='determinant'` creates a determinant matrix with expandable rows and columns
matrix_dimensions	Sets the default number of rows and columns.	Yes	`matrix_dimensions='RxC'` Values are set in the form of rows x columns and support numbers 1 to 8. For example, `matrix_dimensions='3x5'` sets the default dimensions to 3 rows and 5 columns.
matrix_label	Adds a label in plain text format to the matrix.	No	`matrix_label='myLabel'` Values can be set using plain text format. Values for column vectors have the same label, but with a subscript. Values for row vectors have the same label, but with a subscript. Note WaTex, HTML, and symbol space format are not valid in a label; use an HTML table as a workaround.
matrix_static	Turns off expandability of matrix. By default, a matrix is expandable.	No	`matrix_static='true'` Value can only be set to `true`, which changes the matrix from expandable to static.
