WebCorrect option is B) Option A: In a scalar matrix all diagonal elements should be equal but may or may not be equal to 1 only. Therefore Every scalar matrix is not a identity matrix. Option B : In a identity matrix all elements in principal diagonal are equal (equal to 1) which is a form of scalar matrix. Therefore identity matrices are scalar.
WebIs it stupid to consider every scalar and vector as a matrix? Scalars would be the resultant of the multiplication of the number and the identity matrix. To counteract having to specify a size of identity matrix, it would be infinitely large. One could consider all matrices to be infinitely large; the nonexistent slots would be assumed zeroes. sick dude crossword clueWebJan 26, 2015 · A linear operator commuting with all such operators is a scalar multiple of the identity.
