Calculate singular value shapes from time history functions.
ods = svd_T(f)
SVD_T calculates the singular value shapes for a time history function.
T is an imat_fn of time histories. Functions that do not have a datatype of Time Response will be ignored. All of the time histories in T must have the same OrdNumDataType and OrdDenDataType, and must have consistent abscissas. SVD_T will extract a consistent NRES matrix of T from the supplied input.
ODS is an imat_shp containing the Operational Deflected Shapes, which is the U matrix from the SVD calculation. The frequencies of ODS correspond to the singular vectors S from the SVD calculation.
>> ODS = svd_T(t);
>> g = spatial_filter(f,ODS(1:20));
