# ::hwat::math::CheckReflection

Check a given cosine matrix for reflection properties.

## Syntax

::hwat::math::CheckReflection d_matrixList

## Arguments

d_matrixList
The list contains the 9 elements of the cosine matrix – 3 rotation components for X, Y, and Z respectively.

## Returns

Success
d_vectorList, the i, j, k components of the reflection plane.
Failure
{} (matrix does not possess reflection properties)

## Example

::hwat::math::CheckReflection \$theMatrixList

## Comments

The i, j, k components represent the normal to the plane of reflection.
