Familiar properties of numbers extend to these operations on matrices: for example, addition is commutative, that is, the matrix sum does not depend on the order of the summands: A + B = B + A. [9] The transpose is compatible with addition and scalar multiplication, as expressed by (cA) T = c(A T) and (A + B) T = A T + B T. Finally, (A T) T = A.
Consider the system of equations + + = + + = + + = The coefficient matrix is = [], and the augmented matrix is (|) = []. Since both of these have the same rank, namely 2, there exists at least one solution; and since their rank is less than the number of unknowns, the latter being 3, there are an infinite number of solutions.
One of the reasons for the importance of the matrix exponential is that it can be used to solve systems of linear ordinary differential equations.The solution of = (), =, where A is a constant matrix and y is a column vector, is given by =.
The sum and difference of two symmetric matrices is symmetric. This is not always true for the product: given symmetric matrices and , then is symmetric if and only if and commute, i.e., if =.

A teenager has been sentenced to 52 years in prison for fatally stabbing three girls at a children's Taylor Swift-themed event in the United Kingdom last year. Axel Rudakubana, 18, pleaded guilty ...
An active-matrix liquid-crystal display (AMLCD) is an extremely common type of liquid-crystal display (LCD).Having supplanted passive-matrix LCDs in general use, in common vernacular, an active-matrix LCD is also simply referred to as a LCD.
GE multifactorial analysis is a technique used in brand marketing and product management to help a company decide what products to add to its portfolio and which opportunities in the market they should continue to invest in.
