What are the conditions that should be fulfilled to be equal matrix?
Matrices are said to be equal if they have the same number of rows, the same number of columns and their corresponding elements are equal.
What is product of matrix?
In mathematics, particularly in linear algebra, matrix multiplication is a binary operation that produces a matrix from two matrices. The resulting matrix, known as the matrix product, has the number of rows of the first and the number of columns of the second matrix. The product of matrices A and B is denoted as AB.

What is the condition of a matrix?
The condition number of the matrix measures the ratio of the maximum relative stretching to the maximum relative shrinking that matrix does to any non zero vectors.
What does it mean when two matrices are equivalent?
Matrix equivalence is an equivalence relation on the space of rectangular matrices. The matrices can be transformed into one another by a combination of elementary row and column operations. Two matrices are equivalent if and only if they have the same rank.

How to find the condition number of a matrix?
- Choose a matrix norm. Although the choice is problem-dependent, the matrix 2-norm is typically used.
- Evaluate the inverse of A. We need the matrix inverse to find the matrix condition number.
- Calculate ‖A‖ and ‖A−1‖.
- Multiply the norms to find cond(A).
How do you show two matrices are similar?
If two matrices are similar, they have the same eigenvalues and the same number of independent eigenvectors (but probably not the same eigenvectors).
