function ParameterMatrix = zSetSurfaceParamMatrix(ParamMatrix)
% zSetSurfaceParamMatrix - Sets all lens surface parameter data from a 13 column matrix.
%
% Usage : ParameterMatrix = zSetSurfaceParamMatrix(ParamMatrix)
%
% If the matrix passed has fewer than 13 columns, missing columns on the right will be set to zero.
% Returns NaN (not-a-number) if data requests to ZEMAX time out.
