Matrix diagonalis Ii sipan Reэкиыт 0.0p

Matrix diagonalis est matrix quadrata, cuius elementa omnia extra diagonalem principalem zeronis valorem habent. Saepe scribitur:

{\\displaystyle D={\\rm {diag}}(d_{1},d_{2},\\dots ,d_{n})={\\begin{pmatrix}d_{1}&0&\\cdots &0\\\\0&d_{2}&\\ddots &\\vdots \\\\\\vdots &\\ddots &\\ddots &0\\\\0&\\cdots &0&d_{n}\\end{pmatrix}}}

Matrix diagonalis, cui omnes numeri ${\\displaystyle d_{1},d_{2},\\ldots d_{n}}$ aequales sunt, matrix "scalaris" vocatur.^[1]
