No. A scalar matrix can not be a zero matrix
Just a note on separate Qs & As here. I'd stumbled on this group because as I can't understand matrices, I wasn't looking deliberately, but it looks as if another questioner has also asked the same, albeit with the words reversed, and gained a "Yes" and explanation.

What is the definition of a null matrix?
The null matrix is also called the zero matrix. It is a matrix with 0 in all its entries.
Is the scalar matrix is always a identity matrix?
No. A scalar matrix is a diagonal matrix whose main diagonal elements are the same. Only if the diagonal elements are all 1 is it an identity matrix.
Is Zero matrix a null matrix?
Yes.
Is null matrix is diagonal matrix?
Yes.
What is a matrix and a scalar?
A matrix and a scalar is a matrix. S + M1 = M2. A scalar is a real number whose square is positive. A matrix is an array of numbers, some of which are scalars and others are vectors, square of the number is negative. A matrix can be a quaternion, the sum of a scalars and three vectors.
How do you multiply a matrix by a scale?
Multiply each element of the matrix by the scalar.
What is the null matrix?
the matrix whose entries are all 0
What is null matrix?
the matrix whose entries are all 0
What is A constant by which a matrix is multiplied?
It is a scalar multiplier.
How matrix are different from scalar?
A scalar is any single number, like 27, while a matrix contains at least 2 numbers such as [27, 3].
What type of matrix is a vector?
Vector matrix has both size and direction. There are different types of matrix namely the scalar matrix, the symmetric matrix, the square matrix and the column matrix.
What is the difference between zero matrix and null matrix?
there is none you weasel. the only good matrix is revolutions. :)
