WebOrthogonal Matrix: Types, Properties, Dot Product & Examples. Orthogonal matrix is a real square matrix whose product, with its transpose, gives an identity matrix. When two vectors are said to be orthogonal, it means that they are perpendicular to each other. When these vectors are represented in matrix form, their product gives a square matrix. WebAn matrix can be seen as describing a linear map in dimensions. In which case, the determinant indicates the factor by which this matrix scales (grows or shrinks) a region of -dimensional space.. For example, a matrix , seen as a linear map, will turn a square in 2-dimensional space into a parallelogram.That parallellogram's area will be () times as big …
