# getMatrix

**Installation Required:** This functionality requires MATLAB Support Package for Quantum Computing.

## Syntax

## Description

## Examples

## Input Arguments

## Limitations

Because the size of the matrix that represents a quantum circuit or gate operation scales as $${2}^{n}$$-by-$${2}^{n}$$ as the number of qubits

*n*grows, using`getMatrix`

is practical only when*n*is less than about 15.

## Tips

To compare if two circuits perform an equivalent operation, you can use

`getMatrix`

to get the matrix representations of the circuits. If the two matrices are equal, then the circuits are equivalent.
