epäortogonaalisuutta
Epäortogonaalisuus refers to a lack of orthogonality, a concept primarily found in mathematics and physics. In simple terms, orthogonality signifies a state of perpendicularity or independence between elements, such as vectors or functions. When these elements are non-orthogonal, it means they are not at a right angle to each other or they share some form of dependence or overlap.
In linear algebra, vectors are orthogonal if their dot product is zero. If the dot product is
In signal processing and quantum mechanics, epäortogonaalisuus can arise when analyzing or representing signals or states
