Nothing particular if all the 1s are in the first column, for example.
You could have an echelon matrix, but with the information given, it is hard to tell.

What is One of the numbers in a matrix?
Each number is called an entry.
How to write incidence matrix?
An incidence matrix is a mathematical matrix showing a relationship between two different types of objects. The first class can be written as X and the second as Y with one row for each element of X and one column for each element of Y. The entry in row x and column 1 should be 1 if x and y are related to one another. The entry in row x and column 1 should be 0 if they are not related to each other,
What is meant by the word eigenvalue?
The term "eigenvalue" refers to a noun which means each set of values of parameter for which differential equation has a nonzero solution. It can also refers to any number such that given matrix subtracted by the same number and multiply to the identity matrix has a zero determinant.
What does it mean when it says list the first five nonzero multiples of each number?
Take the first number. Add it to itself. Keep adding that number to the total three more times. The first five nonzero multiples of 9 are 9, 18, 27, 36, and 45. Put another way, let each number equal x. The first five nonzero multiples of x are 1x, 2x, 3x, 4x and 5x.

What are the first two things listed in each entry in a dictionary?
The first two things listed in each dictionary entry are usually the word being defined and its pronunciation key.
What is the design matrix?
In a statistical experiment, a design matrix or model matrix is a matrix of the independent or explanatory variables. Each row of the matrix represents the set of values for the variables in one replication of the experiment. Each column represents a different variable. The first column is usually a set of 1s which generates the constant term in the regression analysis.

How do you multiply 3x3 matrices by 1x3 or 3x1?
First of all, if we have any two matrices of sizes mxn and pxq where m, n, p and q are natural numbers, then we must have n=p to be able to multiply the matrices. The result is an mxq matrix. For example, a 3x1 matrix has m=3 and n=1. We can multiply it with any matrix of size 1xq. For example a 2x3 matrix can be multiplied with a 3x1 matrix which has 3 rows and 1 column and the result is a 2x1 matrix. (2x3) multiplies by (3x1) gives a (2x1) matrix. The easy way to remember this is write the dimension of Matrix A and then Matrix B. The two inner numbers must be the same and the two outer numbers are the dimensions of the matrix you have after multiplication. For example Let Matrix A have dimensions (axb) multiply it by matrix B which has dimensions (bxc) = the result is matrix of dimensions ac. Using the trick we would remind ourselves by writing (a,b)x(b,c)=(a,c). This is technically wrong because the numbers are dimensions, but it is just a method to help students remember how to do it. So, a 3x3 matrix can be multiplied by a 3x 1 but not by a 1,3 matrix. How do you do it? Just multiply each entry in the first row of A by each entry in the first column of B and add the products. Do the same for the next row etc. Many (or should I honestly say MOST) people use their fingers and go along row one and then down column one. The add the products of the entries as they do that. Then they do the same for row two and column two etc. It really does help!
What word the Matrix is real?
If each element of a matrix is real then the matrix is real.
How can you integrate a matrix?
You integrate each element of the matrix.
Is matrix polynomial and polynomial matrix same?
No. A matrix polynomial is an algebraic expression in which the variable is a matrix. A polynomial matrix is a matrix in which each element is a polynomial.
