%X In this paper, we give some new necessary and sufficient conditions,for a matrix,whose coefficients are in C*-algebra or are Hilbert space operators, to be: positive.And apply them to get the positive completion of matrices with some coefficient.sunknown and the computation formulas for the square root and the Moors-Penrosegeneralized inverse of operator matrixes.
