to either the linearized phase and coherence plot or the least squares fit in CIFER ® so those
options are not available to the cifxover function.

Again it should be noted that care should be used when employing the 0 flag for inputs as
response names are not assumed by the code. Output information is stored in the same fashion as
cifhq. The first two variables contain the numeric values for the crossover characteristics, and the
last variable has the frequency range of the response.

cifarith:
This utility allows basic arithmetic (+,-,*,/) to be performed on two frequency responses. The
results are saved to a new response file. A very simple example of running the arithmetic function
is shown below:
>> in=cifarith;
>> in.names = {'XVLATSWP_FRE_A0000_AIL_P','XVLATSWP_FRE_A0000_AIL_R'};
>> in.outname = 'test';
>> in.outid = 'arith resp from Matlab';
>> cifarith(in)
Response test written to the database.
