Name of matrices where the first non-zero entry of each row is the last non-zero entry of its column
$begingroup$
Is there a name for matrices where the first non-zero entry of each row is the last non-zero entry of its column?
For example this matrix: $$begin{pmatrix}
0 & bf 1 & 0 & 1 \
bf 1 & 0 & 1 & 1 \
0 & 0 & 0 & bf 1 \
0 & 0 & bf 1 & 0 \
end{pmatrix}$$
Like row echelon form, they allow you to quickly determine the rank of a matrix, but I wasn't able to find how they are called (if they have a name).
