data15p {unfoldr} | R Documentation |
The data set consists of section profile parameters (assumed to come from prolate spheroids) of ellipses fitted to measured particles of an aluminium matrix composite [5] from metallographic analysis. The data set can be used to reconstruct the trivariate spatial (prolate) spheroid distribution.

A matrix of columns: A
(major semi-axis length), C
(minor semi-axis length),
S=C/A
(shape factor), alpha
(polar angle in intersecting plane) and coordinates in the
