Determinants,at .; in other words, if two diagonal square matrices are equivalent, then the product of the diagonal entries of one is the same as the product of the diagonal entries of the other. Once this theorem is proved, we will speak of . determinant of a square matrix, not . determinant.

Matrices with Rational Number Entries,“l(fā)inear substitution” is extended-what was called a linear substitution before is still a linear substitution, but new linear substitutions are allowed. The operation of composition of linear substitutions is defined in the same way as before, and it corresponds in the same way as before to an opera

This subset of patients could represent 5–10% of the total population with this disease (.). Surgical myectomy has been shown to reduce outflow gradie
