Determinant Matrix vmatrix

When to use Determinant Matrix

Creates a matrix enclosed by single vertical bars. In source, start from the exact vmatrix command instead of imitating the rendered glyph with Unicode characters or manual spacing. This keeps the expression editable and gives the renderer enough structure to apply mathematical spacing correctly.

Syntax

vmatrix

The documented syntax belongs to amsmath. Keep every required argument, brace pair, and environment boundary intact when moving the command between an editor, Markdown processor, notebook, or publishing system.

Example

\begin{vmatrix}a&b\\c&d\end{vmatrix}

Rendered output

determinant

Copy and compatibility checks

• Copy vmatrix exactly; changing its case or removing a leading backslash can turn it into plain text.
• Confirm that the destination loads amsmath before relying on this command.
• Render the example once, then inspect grouping, limits, scripts, and spacing before publishing.
