Specifying Arrays of FRD Models Using frd
To specify a K-dimensional array of p-output, m-input FRD models for which
are the lengths of the array dimensions, use
sys = frd(response,frequency,units)
where
•
frequency is a real vector of n frequency data points common to all FRD
models in the LTI array.
•
response is a p-by-m-by-n-by- -by- -by- complex-valued
multidimensional array.
•
units is the optional string specifying 'rad/s'or'Hz'.
NotethatforspecifyinganLTIarrayofSISOFRDmodels,
response can also
be a multidimensional array of 1-by-n matrices whose remaining dimensions
determine the array dimensions of the FRD.
