The robust pole assignment approach for linear time-invariant multivariable system is investigated based on the properties of normal matrix. By the combination of frequency-domain and time-domain ...

For the case where the multivariate normal population does not have null correlations, we give the exact expression of the distribution of the sample matrix of correlations R, with the sample ...

This correspondence addresses the asymptotic normal distribution of the sample mean and the sample covariance matrix of mixed spectra time series containing a sum of sinusoids and a moving average (MA ...

It is known that if A∈Mn is normal (AA*=A*A) , then AA￣=A￣Aif and only if AAT=ATA. This leads to the question: do both AA￣=A￣A and AAT=ATA imply that A is normal? We give an example to show that this ...
