Can the rank of a matrix be zero
WebThe rank of a 5×3 matrix A. can be any number from zero to three. B. must be zero. Q. can be any number from zero to five. D. can be any number from two to five. E. is three. … WebTherefore, the rank of 𝐴 must be less than or equal to the smaller of these numbers, which is two. Recall also that the rank of 𝐴 is equal to zero if and only if 𝐴 is the zero matrix. This matrix clearly isn’t the zero matrix. Therefore, its rank cannot be zero.
