I have come across some papers in which the authors have replaced a matrix element with the ' * ' symbol and I would like to know what it means. Attached, along with is a paper where you will find a similar instance in the page 2858. What does that signify?
Dear Biswajit,
I agree with Oscar for this particular case, but I would like to add that more generally, I think the symbol just means "omitted" (here it is probably used in order to typeset the matrix on a single line). Sometimes I've seen a boldface "\times" symbol used for the same purpose.
Cheers,

If I'm reading it correctly, it is a symmetric matrix. So the value of the star has the same value as the opposite corner.

Dear Biswajit,
I agree with Oscar, the paper typeset is two columns style, the authors have replaced a matrix element with the ' * ' symbol for save area.

Dear Biswajit,
It is better that this symbol has been defined in the document. Oscar says true for many cases but in general, the value of the star is transpose of the opposite corner for real matrices. You often see this notation in LMIs for lower triangular part of matrix.
Thank You for the response Mr. Ali,
I had wondered once if the '*' symbol stood for transpose of a conjugate matrix which is usually the case in text books but since no complex quantity is involved in this one so it may as well denote the transpose of the opposite corner element.. I will now have work it out to see what actually it denotes..
The "star" represents matrix elements that can be interpreted from the matrix structure, being symmetric, anti-symmetric, Hankel, Toeplitz, etc.
The '*' symbol stand for conjugate transpose must appear outside at the top right-hand corner of the matrix.
Dear Deb
I have try the algorithms technique for a decade of the years
For me that have tried the techsource algorithms technique
it just a numbers of not more than thousand data
there are also can be calculated as a numbers of 0.0006 for the error for the
radio technologies tireless data transfers systems man
Thanks Wiwat,
I had missed that perspective.
Mr mohd arinal,
I am not getting what you are trying to mean. Is it relevant to the question I have asked ?
i have tried this but we need to understand all of this
i'm soorry because i have back and forget all about this mem
