Info

The template sets all values to the defaults found when the arithmetic utility in CIFER ® is first run. For example, all scale factors are set to 1, the operation is multiplication, and the source and destination point to the database. Any of these values can be modified either by changes to the appropriate field in the structure or by using the field name and value as a pair of inputs. The above example could be compressed into one call as follows. There are no output variables for this function, and as before the ‘toscrn’ field allows the user to turn off the printed return information. >> cifarith(0,'names',{'XVLATSWP_FRE_A0000_AIL_P', 'XVLATSWP_FRE_A0000_AIL_R'},'outname','test','outid','arith resp from Matlab','toscrn','off') cifplot: The cifplot function is the MATLAB command line call for CIFER's utility 19, the frequency response plotting. A basic set of calls to cifplot are shown below: >> in = cifplot; >> in.array(1:3) = [1,2,3]; >> in.names(1) = {'XVLATSWP_FRE_A0000_AIL_P'}; >> cifplot(in); Reading data ....... Plotting successful After this call, the standardized CIFER ® plot would be displayed to the screen. As with the previous functions, the call can be simplified using name-value pairs as input. The previous example could be reduced as follows. There are no output variables for this function. >> cifplot(0,'array',[1,2,3,0,0],'names', {'XVLATSWP_FRE_A0000_AIL_P','','','','',''}) Reading data ....... Plotting successful 80
CIFER ® support utilities: Three functions are available to facilitate the retrieval of data from the CIFER ® database. The getfr function, when given a frequency response name, will return arrays for frequency, magnitude, phase and so on. The other function, writefr, allows the user to change values in these arrays and pass them back in to be saved to the CIFER ® database. The third function is called caselist and allows the user to query the database for which cases are stored for a particular program. Due to the simplicity of these functions, structures are not used to input data as is done for the other CIFER ® programs and utilities. Thus, these functions do not have the empty call feature that returns a list of structure field data types. They do still include help documentation which can also be found in Appendix G. getfr and writefr: The getfr function is designed to give users access to all the arrays that make up a full frequency response. The most complete call, shown below, will bring back arrays of all 10 frequency response fields. The order in which these are returned is fixed; therefore if only coherence were desired, variables to hold information for frequency, magnitude and phase would still be required as shown in the second function call, which only returns four of the frequency response data fields. >> name = 'XVLATSWP_COM_ABCDE_AIL_P'; >> [frq,mag,pha,coh,gxx,gyy,gxy,rel,img,err] = getfr(name); >> [frq,mag,pha,coh] = getfr(name); Frequency responses can also be written back into the CIFER ® database through the writefr function. The example below shows the creation of a new frequency response with all 10 data arrays. Again, the order is fixed and, as above in the getfr example, not all the inputs need be provided. If all inputs are not provided the user should keep in mind that CIFER ® will not have access to any unspecified information in the event it must make calculations with the new responses. The response names do not have to conform to CIFER ® naming conventions, though doing so will help track new responses. >> name = 'NEW_FREQUENCY_RESPONSE'; >> writefr(name, frq, mag, pha, coh, gxx, gyy, gxy, rel, img, err); 81
