WebExample: for a 2×4 matrix the rank can't be larger than 2. When the rank equals the smallest dimension it is called "full rank", a smaller rank is called "rank deficient". The rank is at least 1, except for a zero matrix (a matrix made of all zeros) whose rank is 0. WebIf the matrix has more rows than columns, a row of all zeros does not imply a free variable. For example: $$ \left[\matrix{1 & 2\cr 3 & 4\cr 0 & 0\cr}\right]$$ One way you find free variables is: put the matrix into row-echelon form, then any column that does not contain the first nonzero entry of any row corresponds to a free variable.
