Linear algebra

4. the scalar value computed for a given square matrix.
8. a matrix with an equal number of rows and columns.
9. The table of numbers arranged in rows and columns
11. matrix consisting of the coefficients of the variables in a set of linear equations
13. the set of all n-dimensional column vectors x such that Ax = 0.
15. a type of diagonal matrix that the diagonal elements are equal or same.

1. matrix, which on multiplication with the given matrix gives the multiplicative identity.
2. the determinant of some smaller square matrix, cut down from A by removing one or more of its rows and columns.
3. a combination of all the linearly independent vectors.
5. interchanging its rows into columns or columns into rows
6. 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.
7. the dimension of the vector space generated by its columns.
10. the special set of scalar values that is associated with the set of linear equations most probably in the matrix equations.
12. a special type of square matrix where all the values above or below the diagonal are zero
14. The term that refers to the stair-step pattern formed by the nonzero elements of the matrix.
