Down
- 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.
