- MatrixRank[ <Matrix> ]
- Returns the rank of given matrix.
- Examples:
MatrixRank[{{2, 2}, {1, 1}}]yields 1.MatrixRank[{{1, 2}, {3, 4}}]yields 2.- Let
A = {{1, 2, 3}, {1, 1, 1}, {2, 2, 2}}be a 3x3-matrix.MatrixRank[A]yields 2.
Hint: In the 
CAS View this command also works with undefinde variables.
- Example:
MatrixRank[{{1, 2}, {k*1, k*2}}]yields 1.
