How to solve a square matrix

WebThe same formula will work here, as long as is invertible, has a square root in and the matrices and are commuting with each other. as an equation over has no solution in . But can be thought of as matrices with real entries. Hence matrix quadratic equation need not have a solution even in commutative case. Here , and . WebA square root of a diagonal matrix is just the square roots of the diagonal entries, so we have B = (4 − 3 3 4)(√50 0 0 √25)(4 − 3 3 4) − 1 = 1 5( 9 + 16√2 − 12 + 12√2 − 12 + 12√2 16 + 9√2). Here we used √50 = 5√2, √25 = 5, and a quick formula for the inverse of a 2 × 2 matrix: (a b c d) − 1 = 1 ad − bc( d − b − c a).
