Left-aligned determinant:

Handwriting matrix:

Printing matrix:

\cdots horizontal ellipsis. Effect:

\ ellipsis in the diagonal direction of point d (from upper left to lower right). Effect:

\ v vertical ellipsis. Effect:

\ldots is an ellipsis aligned with the bottom line of the text. Effect:

The ellipsis in the diagonal direction (from upper left to lower right) is not perfect, but it is barely available. Effect:

Ellipsis matrix:

A vertical line can be generated in the matrix by adding a small vertical line between aligned letters, and a horizontal line can be generated by inserting a line between rows.
