function FieldPoints = zSetFieldMatrix(FieldType, FieldDataMatrix)
% zSetFieldMatrix - sets all field points from a matrix
%
% Usage : FieldPoints = zSetFieldMatrix(FieldType, FieldDataMatrix)
%
% Create and pass a matrix having columns 8 columns of field data xf, yf, wgt, vdx, vdy, vcx, vcy, van
% If the matrix has fewer columns, it will be assumed that columns on the right are zero.
% The matrix can have from 1 to 12 rows.
% The function returns the number of field points set.
% The parameter FieldType is an integer; either 0, 1, or 2, for angles in degrees, object height, or paraxial image height,
% respectively, 3 for real image height.
