When is it important for a matrix to be square?
In the context of matrix algebra there are more operations that one can perform on a square matrix. For example you can talk about the inverse of a square matrix (or at least some square matrices) but not for non-square matrices.
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 calculate complex number using matrix?
A complex number a + bi, can be represented as a 2x2 matrix: [a -b] [b a ] or [a b ] [-b a ] , just keep the same notation throughout your work. See the wikipedia article on Complex Numbers, and the related link for some more information.
Is a singular matrix an indempotent matrix?
A singular matrix is a matrix that is not invertible. If a matrix is not invertible, then:• The determinant of the matrix is 0.• Any matrix multiplied by that matrix doesn't give the identity matrix.There are a lot of examples in which a singular matrix is an idempotent matrix. For instance:M =[1 1][0 0]Take the product of two M's to get the same M, the given!M x M = MSo yes, SOME singular matrices are idempotent matrices! How? Let's take a 2 by 2 identity matrix for instance.I =[1 0][0 1]I x I = I obviously.Then, that nonsingular matrix is also idempotent!Hope this helps!
Advantages and disadvantages of using adjacency list over adjacency matrix?
Advantages are that you can see the arc lengths disadvantages some times it doesn't work because of insufficient vertices's or arcs.
What are some reasons for using beverages?
It encourages hydration.
What are some of the reasons for not using re-solidified sample for confirmation of melting point?
I suppose that the crystalline structure was disturbed during melting and a new test on this sample may offer an erroneous result.

What are some reasons for someone using heroin?
They are addicted to it or just want a kick from it.
What is the difference between strong and weak matrix organisational structure?
The weak matrix. In this case a project manager oversees staff from different functions but still reports in to his or her functional manager. Such a structuring of the project allows some engagement of those with a stake in the project and enhances the possibility for communication across functional areas - but it is still hierarchical and for this reason retains most of the problems associated with a functional organisation. The strong matrix - In the strong matrix the project manager is independent of functional management. Indeed in this model it is the role of functional managers to support the project by providing technical expertise and assigning resources as and when required. Of course in this structure there is potential for conflict between the project manager and the functional manager over resource assignment and cost allocation - as a result excellent communication, strong relationships and a flexible working culture are required.
What are the reasons for using Photoshop and airbrushing on photos?
Some reasons for using Photoshop would be if someone wanted whiter teeth they could fix it or even if they had a little skin break out they could remove unwanted blemishes.
