solve_poisson

Arguments:

• "laplacian_command",_nb_iterations>=0,_time_step>0,_nb_scales>=0

Description:

Solve Poisson equation so that applying laplacian[n] is close to the result of laplacian_command[n].

Solving is performed using a multi-scale gradient descent algorithm.
If nb_scales=0, the number of scales is automatically determined.

Default values:

nb_iterations=60, dt=5 and nb_scales=0.
