Braced Matrix Bmatrix

When to use Braced Matrix

Creates a matrix enclosed in braces. In source, start from the exact Bmatrix 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

Bmatrix

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{Bmatrix}a&b\\c&d\end{Bmatrix}

Rendered output

matrix in braces

Copy and compatibility checks

• Copy Bmatrix 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.
