Once the cofactor matrix C(i,j) is computed, the result is used to calculate the determinant of A. in our case, A is 4×4 a complex matrix. Theorem 1: if A is a matrix. Choose any row, say row i, then, ...

To make the system work, the researchers designed new versions of glucose dehydrogenase, an important partner for the cofactor. Their engineered version has more electrostatic interactions with ...
