ROWBIND(x;y) stacks matrices
y vertically i.e. forms the matrix [
y′]′. The setting for
y may also be a variate (representing a single-column matrix), a scalar (representing a one-by-one matrix) or a pointer of variates (specifying a matrix with a column for each variate in the pointer);
y must have the same number of columns.
