  • Abstract
    The column rank of an m by n matrix A over the nonnegative reals is the dimension over the nonnegative reals of the column space of A. We compare the column rank with the factor rank of matrices over the nonnegative reals. We also characterize the linear operators which preserve the column rank of matrices over the nonnegative reals.
