Small Matrix Environment smallmatrix

When to use Small Matrix Environment

Creates a compact matrix suitable for inline mathematics. In source, start from the exact smallmatrix 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

smallmatrix

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

\left(\begin{smallmatrix}a&b\\c&d\end{smallmatrix}\right)

Rendered output

inline matrix

Copy and compatibility checks

• Copy smallmatrix 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.
