Howdy all - new newsgroup user here.

I'm attempting to run a principal components analysis on a 315-
variable x 366 observation array, but whenever I try to run PCOMP, I
get the following error message....

% TRIQL: Too many iterations in tqli.
% Error occurred at: EIGENQL 122
/Applications/itt/idl64/lib/eigenql.pro
% PCOMP 119
/Applications/itt/idl64/lib/pcomp.pro
% PCA_4 17 /Users/mcneel/pca_4.pro
% $MAIN$
% Execution halted at: PCA_4 17 /Users/mcneel/
pca_4.pro

Is my 315x366 matrix too much for PCOMP to handle? Can anyone lend a
helping hand?

Thanks in advance, -APM.
