    Only Rank of a zero matrix is zero.If a matrix is non zero matrix, then the rank of the matrix can never be zero.

    Yes. But it happens only in the case of a zero matrix. Rank of a matrix is the number of non-zero rows in the row echelon form. Since in a zero matrix, there is no non-zero row, its rank is 0.
