  1. 2. This is a rectangular array of mn real (or complex) numbers arranged in m horizontal rows and n vertical columns.
  2. 4. This is a type of linear matrix in which the answers of a system of equations are combined with an expressions.
  3. 5. If A and B are n-vectors, then what is the sum of the products of corresponding entries.
  4. 6. In this type of matrices, m and n are equal to each other, for example, 5 * 5.
  5. 7. In this case the corresponding components of the matrices are collected.
  6. 8. A diagonal matrix A=[aij], for which all terms on the main diagonal are equal, that is, aij=c for i=j and aij=0 for i and j is not equal, is called a ...
  7. 9. In this case, the relevant components of the matrices are removed.

  1. 1. This applies to the product of real numbers and matrices. this is the method by which each record in the matrix is multiplied by a given real number.
  2. 3. In linear algebra, this is an operator which flips a matrix over its diagonal; that is, it switches the row and column indices of the matrix A by producing another matrix, often denoted by AT
  3. 5. This is type of square matrix .All the elements are zero except matrix's diagonal
