projektionsmatris
A projection matrix, often referred to as a projektionsmatris in Swedish, is a mathematical tool used in linear algebra and computer graphics to represent a projection from one space to another. It is typically a square matrix that maps a vector space onto a subspace, effectively "projecting" the original space onto the subspace.
Projection matrices are widely used in various fields, including computer graphics, machine learning, and data analysis.
In linear algebra, projection matrices are used to decompose a vector space into a direct sum of
Projection matrices are also used in machine learning and data analysis to reduce the dimensionality of data.
In summary, a projection matrix is a mathematical tool used to represent a projection from one space
