The number of rows and the number of columns in a matrix. For example, a 3×4-dimensional matrix has 3 rows and 4 columns.
There are three elementary row operations:
The matrix
I = ![]() ![]() ![]() |
A way of representing data in a rectangular array.
A = ![]() ![]() ![]() |
The form of a matrix in which the first m×m entries form the
identity matrix:
![]() ![]() ![]() |
The process through which a matrix is converted to reduced row-echelon form, using elementary row operations.
A single constant, variable, or expression.
