First we need to ask what you mean by a matrix equalling a number? A matrix is a rectangular array of numbers all of which might be zero and this is called the zero matrix. We can take the determinant of a square matrix such as a 3x3 and this may be zero even without the entries being zero.

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 it possible to multiply a 3 X 2 matrix and a 2 X 3 matrix?
The first matrix has 3 rows and 2 columns, the second matrix has 2 rows and 3 columns. Two matrices can only be multiplied together if the number of columns in the first matrix is equal to the number of rows in the second matrix. In the example shown there are 3 rows in the first matrix and 3 columns in the second matrix. And also 2 columns in the first and 2 rows in the second. Multiplication of the two matrices is therefore possible.
Are there any math words beginning with z?
Zero Matrix Zero of a Function Zero Slope
What does zero minus negative three equal?
"minus zero" is the same as plus zero in that it makes no difference to the sum. So the answer is -3.
What is the inverse of the matrix 3?
It is the matrix 1/3It is the matrix 1/3It is the matrix 1/3It is the matrix 1/3
What is a zero matrix?
A zero matrix is a matrix in which all of the entries are zero.
What is the definition of zero matrix?
Zero Matrix When all elements of a matrix are zero than the matrix is called zero matrix. Example: A=|0 0 0|
Is there any matrix called as zero matrix?
ya yes its there a matrix called zero matrix
Is Zero matrix a null matrix?
Yes.
What is a sparse matrix?
A sparse matrix is a matrix in which most of the elements are zero.
What is zero matrix?
it is the matrix consisting of all 0s
What is the definition of a skew-Hermitian matrix?
Skew-Hermitian matrix defined:If the conjugate transpose, A†, of a square matrix, A, is equal to its negative, -A, then A is a skew-Hermitian matrix.Notes:1. The main diagonal elements of a skew-Hermitian matrix must be purely imaginary, including zero.2. The cross elements of a skew-Hermitian matrix are complex numbers having equal imaginary part values, and equal-in-magnitude-but-opposite-in-sign real parts.
Prove that a matrix which is both symmetric as well as skew symmetric is a null matrix?
Let A be a matrix which is both symmetric and skew symmetric. so AT=A and AT= -A so A =- A that implies 2A =zero matrix that implies A is a zero matrix
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.
What is a fraction of 3 over 0 equal?
It is not equal to anything. Division by zero is not a valid operation.
What are the Idiosyncrasies of matrix algebra?
idiosyncrasies of matrix are the differences between matrix algebra and scalar one. i'll give a few examples. 1- in algebra AB=BA which sometimes doesn't hold in calculation of matrix. 2- if AB=0, scalar algebra says, either A, B or both A and B are equal to zero. this also doesn't hold in matrix algebra sometimes. 3- CD=CE taking that c isn't equal to 0, then D and # must be equal in scalar algebra. Matrix again tend to deviate from this identity. its to be noted that these deviations from scalar algebra arise due to calculations involving singular matrices.
Why do you need a zero in the place value system?
Zero plays a big role in place value. For example how would you express 3 thousand if you do not use zero or 3 thousandth without zero after the decimal point. Without the zero 3 thousand will just be equal to 3 and 3 thousandth will just be equal to .3
