algebra

1. a special type of square matrix in which all values above or below the main diagonal are zero.
4. . matrix consisting of the coefficients of the variables in a set of linear equations.
8. the determinant of some smaller square matrix, cut down from A by removing one or more of its rows and columns.
11. the special set of scalar values that is associated with the set of linear equations most probably in the matrix equations.
12. with an equal number of rows and columns.
14. the scalar value computed for a given square matrix.

2. elements are equal to or equal to one.
3. In linear algebra, is the dimension of the space formed by the columns of the matrix A.
4. the number you get when you remove the column and row of a designated element in a matrix, which is just a numerical grid in the form of rectangle or a square.
5. An m x n matrix, where m is the number of rows and n is the number of columns, if and only if n = 1.
6. matrix, which on multiplication with the given matrix gives the multiplicative identity.
7. is a matrix in basic linear algebra where the off-diagonal entries are all zero.
9. An m x n matrix, where m is the number of rows and n is the number of columns, if and only if m = 1
10. the set of all n-dimensional column vectors x such that Ax = 0.
13. interchanging its rows into columns or columns into rows.
