<h2>Syntax</h2><p><tt>Y = sqrtm(X)</tt></p>
<h2>Description</h2>
<p>
<tt>sqrtm(X)</tt> computes the matrix square root of a quaternion matrix.
The algorithm used is based on calling the MATLAB&reg; <tt>sqrtm</tt> function
on an adjoint matrix, and is therefore not accurate for larger matrices.
The accuracy may be checked by squaring the result using <tt>^</tt>.
