Laplacian of a Vector Field

 Description Calculate the Laplacian of a vector field.

Define the coordinate system.

 > $\mathrm{VectorCalculus}\left[\mathrm{SetCoordinates}\right]\left({\mathrm{cartesian}}\left[{x}{,}{y}{,}{z}\right]\right):$

Define the vector field.

 >
 $\left({x}{}{{y}}^{{2}}\right){\stackrel{{_}}{{e}}}_{{x}}{+}{4}{}\sqrt{{y}}{\stackrel{{_}}{{e}}}_{{y}}{-}{\left({{ⅇ}}^{{z}}\right)}^{{2}}{\stackrel{{_}}{{e}}}_{{z}}$ (1)
