In linear algebra, a diagonal matrix is a matrix with all zero entries from the main diagonal. This term usually refers to a square matrix. The elements of the main diagonal can be either zero or nonzero. For example, A=[100030006] What is a Symmetric Matrix? The matrix will be known ...

I define a very simple type for a matrix: type MyMatrix integer :: n=0 complex(dp), allocatable :: v(:,:) end type MyMatrix Then, operations turn out
The first is for the Z-matrix whose row sums are all non-negative. The non-singularity condition for this matrix is that at least one positive row sum exists in any principal submatrix of the matrix. The second is for the Z-matrix A which satisfies Ax ≥ 0 where ∃x > 0. Let a...
What is the inverse in matrices? The inverse of a square matrix is some other matrix, which when multiplied together, the result is the identity matrix. Note that this is true for multiplying from the left or right. Algebra II: High School ...
If a matrix has m rows and n columns, then it will have m × n elements. A matrix is represented by the uppercase letter, in this case, 'A', and the elements in the matrix are represented by the lower case letter and two subscripts representing the position of the element in the ...
determinant, in linear and multilinear algebra, a value, denoted det A, associated with a square matrix A of n rows and n columns. Designating any element of the matrix by the symbol arc (the subscript r identifies the row and c the column), the determinant is evaluated by finding the ...
If you combine different integer types in a matrix (e.g., signed with unsigned, or 8-bit integers with 16-bit integers), all elements of the resulting matrix are given the data type of the leftmost element. Combining Integer and Noninteger Data ...
