A matrix that has rank min(m, n) is said to have full rank; otherwise, the matrix is rank deficient. Only a zero matrix has rank zero. f is injective (or "one-to-one") if and only if A has rank n (in this case, we say that A has full column rank). f is surjective (or "onto") if and only if A has rank m (in this case, we say that A has full row ...
The non-commissioned officer status begins with the rank of 'Lance Naik.' Company Quartermaster Havildar, Company Havildar Major, Battalion Quartermaster Havildar, and Battalion Havildar Major are company/battalion appointments held by senior Havildars. [3] The ranks of Sowar, Daffadars, and Risaldars are utilized in the armoured corps.
Applicable to: m-by-n matrix A of rank r Decomposition: A = C F {\displaystyle A=CF} where C is an m -by- r full column rank matrix and F is an r -by- n full row rank matrix Comment: The rank factorization can be used to compute the Moore–Penrose pseudoinverse of A , [ 2 ] which one can apply to obtain all solutions of the linear system A x ...
The Pakistan Navy ranks and insignia are the military insignia used by the Pakistan Navy. They are used to identify their roles as commanding officers and varies with their responsibilities. [ 1 ] Pakistan shares a rank structure similar to that of the United Kingdom .

Every finite-dimensional matrix has a rank decomposition: Let be an matrix whose column rank is . Therefore, there are r {\textstyle r} linearly independent columns in A {\textstyle A} ; equivalently, the dimension of the column space of A {\textstyle A} is r {\textstyle r} .
It is the highest rank in the armed services, immediately ranks above three-star lieutenant general and below five-star field marshal. Since it is denoted by a four-star rank, it is equivalent to the rank of admiral and air chief marshal. [4] The Pakistan army is led by a senior four-star general as Chief of Army Staff (COAS).
Depending on circumstances and the army in question, these ranks may be considered to be equivalent to a "full" general or to a field marshal five-star rank (NATO OF-10). The rank of general came about as a "captain-general", the captain of an army in general (i.e., the whole army).
