    gradient/divergence

    Hi,

    I have a problem with implementation of level set algorithm (MATLAB).

    Could you please help me simplify those two equations:

    div(dp(\left | grad(\phi ) \right |)grad(\phi))

    div(g\frac{grad(\phi)}{\left | grad(\phi) \right |})

    where dp is a function, g, and phi are n x m matrices and || is a norm.

    Thanks
