Create correlation table between test and analysis modes
table = correlation_table(st,sg,tam)
table = correlation_table(st,sg,tam,percent)
table = correlation_table(st,sg,tam,percent,file)
CORRELATION_TABLE creates an extended comparison table that includes the cross-RSS (CRSS) of modes within a specified percentage in frequency of the best correlated mode, and the CRSS of all modes. These tables are output to an excel spreadsheet.
ST is an imat_shp containing the test shapes.
SG is an imat_shp containing the FEM shapes.
TAM is a structure containing the TAM matrix. It must have at least the .aset and .mass fields.
FILE is a string containing the name of the Excel file to export. If not supplied or it is empty, the Excel file will not be generated.
PERCENT is a scalar percentage specifying the frequency range on either side of each best fit analysis mode frequency to include in the calculation. The default is 5%. A value of 100 specifies that all of the FEM modes should be included when computing the RSS.
TABLE is a structure containing the following fields, each of which contains a comparison table matrix. See COMPARISON_TABLE for a description of the first N-2 columns of each matrix. The last two columns of each matrix contain the RSS values for the modes within the specified percentage, and the RSS of all of the modes, respectively.
