By counting, the nonzero elements in the matrix are 19
How many nonzero elements are in the matrix
From the question, we have the following parameters that can be used in our computation:
The matrix (see attachment)
A nonzero element in a matrix is an element that is not equal to zero.
This means that
- A matrix is considered nonzero if it contains at least one nonzero element.
- If all the elements of a matrix are zero, it is called a zero matrix.
Using the above as a guide, we have the following:
There are 19 elements that are nonzeros
Hence, the nonzero elements in the matrix are 19
