CE ÎNSEAMNĂ NORMAL MATRIX ÎN ENGLEZĂ?
Matrice normală
În matematică, o matrice pătrată complexă A este normală dacă A * este conjugatul care transpune A. Adică, o matrice este normală dacă se comută cu transpunerea ei conjugată. O matrice reală A satisface A * = AT și, prin urmare, este normală dacă ATA = AAT. Normalitatea este un test convenabil pentru diagonabilitate: o matrice este normală dacă și numai dacă este unitar ca o matrice diagonală și, prin urmare, orice matrice A care satisface ecuația A * A = AA * este diagonalizabilă. Conceptul matricelor normale poate fi extins la operatorii normali pe spațiile Hilbert dimensionale infinite și la elementele normale din algebrele C *. Ca și în cazul matricei, normalitatea înseamnă că comutativitatea este păstrată, în măsura posibilului, în cadrul non-comutativ. Acest lucru face ca operatorii obișnuiți și elementele normale ale algebrilor C * să fie mai ușor de analizat.

If A A* = A*A, then A is said to be a normal matrix. A matrix U such that U*U = /,
that is, U'1 = U*, is normal. Following G. Frobenius, we call it a unitary matrix (in
the following discussion, we shall call it simply a u-matrix). A matrix H such that H
