Oyster_Z_matrices {shelltrace}

Function that calculates matrices of Z-values for all sub-increments and all X-values

Description

Function that calculates Z-values that form the edge of the shell in terms of distance from the X-axis in direction of the width of the shell. de Winter, N. J. (2017) <doi:10.5194/gmd-2017-137>

Usage

Oyster_Z_matrices(IncG, subincr_matrix)

Arguments

IncG

Matrix of X- and Y-coordinates of all interpolated sub-increments

subincr_matrix

Data frame that contains characteristics of every sub-increment

Details

Z-values are calculated using the standard formulae of an ellipse, the parameters calculated in "Oyster_Oval_parameters" and the X-coordinates of each sub-increment

Value

Z-mat

Matrix of Z-values for each X-value and each sub-increment
