Calculate The Matrix Of Angles of Incidence

Description

Calculates the matrix that contains the angles of incidence for the the raypath for each travel time measurement. The matrix has ncols = number of layers in the velocity model, and nrows = number of travel time measurements.

Usage

thetamatrix(z, v, bot, hoffset)

Arguments

z array (length = k) of depth to each travel time measurement.
v array (length = n) of velocities that correspond to each layer defined by bot.
bot array (length = n) of the depth to bottom of each layer such that the bottom of the last layer is the location the source (or receiver).
hoffset k by n numeric value of horizontal offset from borehole at surface.

Value

k by n matrix of angles of incidence.
