Laplacian : laplacian
laplacian takes two arguments : an
expression F of n real variables and a vector of these variable names.
laplacian returns the laplacian de F, that is the sum of all second
partial derivatives, for example in dimension n = 3:
Example
Find the laplacien of
F(x, y, z) = 2x2y - xz3.
Input :
laplacian(2*x^
2*y-x*z^
3,[x,y,z])
Output :
4*y+-6*x*z
