comparison_table


Purpose

Generate a mode shape comparison table.

Syntax

CTableOtg = comparison_table(st,sg,Otg,minvalue)

Description

COMPARISON_TABLE generates a comparison table between two sets of mode shapes - usually test (ST) and analysis (SG).

The inputs to this function are two imat_shp objects, ST and SG, an orthogonality or MAC matrix generated using the ORTHO function, OTG, and a minimum acceptable cross-ortho or cross-mac value, MINVALUE expressed in percent (0-100%).

COMPARISON_TABLE returns a listing of all mode shape pairs in ST and SG that have associated cross-MAC or cross-Orthogonality entries greater than MINVALUE Each row of the output, CTABLEOTG, contains 6 columns of information:

CTableOtg(:,1)            ST Mode Number

CTableOtg(:,2)            SG Mode Number

CTableOtg(:,3)            ST Frequency

CTableOtg(:,4)            SG Frequency

CTableOtg(:,5)            %Diff Frequency

CTableOtg(:,6)            Cross-Orthogonality

Examples

>>% Import Mode Shapes
>> sg=readadf
>> st=readadf
>>% Run the ortho command (with or without a mass substructure)
>> [MACtg]=ortho(st,sg);
>>% Set minvalue = 80 %
>> minvalue=80;
>>% Then run COMPARISON_TABLE
>> [CTableMACtg]=comparison_table(st,sg,MACtg,minvalue)
