For the cases where has full row or column rank, and the inverse of the correlation matrix ( for with full row rank or for full column rank) is already known, the pseudoinverse for matrices related to can be computed by applying the Sherman–Morrison–Woodbury formula to update the inverse of the ...
The following technologies are related to APC and in some contexts can be considered part of APC, but are generally separate technologies having their own (or in need of their own) Wiki articles. Statistical process control (SPC), despite its name, is much more common in discrete parts manufacturing and batch process control than in continuous ...
The Council for the Indian School Certificate Examinations (CISCE) [1] is a non-governmental privately held national-level [2] [3] board of school education in India that conducts the Indian Certificate of Secondary Education (ICSE) Examination for Class X and the Indian School Certificate (ISC) for Class XII.

Others, such as matrix addition, scalar multiplication, matrix multiplication, and row operations involve operations on matrix entries and therefore require that matrix entries are numbers or belong to a field or a ring. [8] In this section, it is supposed that matrix entries belong to a fixed ring, which is typically a field of numbers.
The smallest (and unique up to rotation and reflection) non-trivial case of a magic square, order 3. In mathematics, especially historical and recreational mathematics, a square array of numbers, usually positive integers, is called a magic square if the sums of the numbers in each row, each column, and both main diagonals are the same.
Diagonal matrices D and E, and unitary U and V, are not necessarily unique in general. Comment: U and V matrices are not the same as those from the SVD. Analogous scale-invariant decompositions can be derived from other matrix decompositions; for example, to obtain scale-invariant eigenvalues. [3] [4]
The iterative proportional fitting procedure (IPF or IPFP, also known as biproportional fitting or biproportion in statistics or economics (input-output analysis, etc.), RAS algorithm [1] in economics, raking in survey statistics, and matrix scaling in computer science) is the operation of finding the fitted matrix which is the closest to an initial matrix but with the row and column totals of ...
M59 APC D-cisive. The M59 was an American armored personnel carrier that entered service in the spring of 1954 replacing the M75. It had three key advantages over the M75; it was amphibious, had a lower profile, and was considerably cheaper to produce. Production ended in 1960, by which time approximately 6,300 had been built.
