| <div class="block">A buckle method for calculating derivative and coordinate transformation in a single step. |
| The transform result is stored in the given destination array, and the derivative matrix |
| is returned. Invoking this method is equivalent to the following code, except that it may |
| execute faster with some <code>MathTransform</code> implementations: |
| |
| <blockquote><pre>DirectPosition ptSrc = ...; |
| DirectPosition ptDst = ...; |
| Matrix matrixDst = <b>derivative</b>(ptSrc); |
| ptDst = <b>transform</b>(ptSrc, ptDst);</pre></blockquote></div> |

| <dd><code>srcOff</code> - the offset to the point to be transformed in the source array.</dd> |
| <dd><code>dstPts</code> - the array into which the transformed coordinate is returned.</dd> |
