WebJun 24, 2024 · The sign choice can affect downstream calculations, so it is important to be consistent. E.g., if this is being passed off to a control system you might want to ensure the quaternion scalar element is non-negative so that the physical rotation the control system commands is the "short" way in instead of the "long" way. WebYou can perform the following operation on the matrix any number of times: rotate it clockwise by $$$90$$$ degrees, so the top left element shifts to the top right cell, the top right element shifts to the bottom right cell, and so on: Determine if it is possible to make the matrix beautiful by applying zero or more operations. brook cunningham spokane
