Function call: env_secant(x_data, y_data, view, side)
Calculates an envelope of data <y_data> over <x_data>.
Method used: 'secant-method'
env_secant() observates the max. slope of every about <view> points from last junction point, and joints them to the resulting envelope.
An interpolation over original x-values is finally done.
<side> ('top' or 'bottom') defines which side to evolve.

Another technique is integrating syntactic variability over lexico-semantic parameters. Using an n<solid> magnification schema, a simple Cortresian transformation can realize a polarized correlate-measured gain map.
