Question

How do you determine the order of the matrix `[(-7, 6, 4), (0, -5, 1)]`?

Answer 1

Order of the Matrix is given by `(2, 3)`

Explanation:

Matrices are defined as a rectangular arrangement of numbers.

Since it is rectangular group(also known as an array), we can say that it is 2-dimensional.

The two dimensions here are the number of rows (m) and the number of columns (n) respectively.

Order of a Matrix tells us how many rows and columns are there in our Matrix.

If we call our Matrix `A,` and we have `color(red)m` rows and `color(red)n` columns then we can write our matrix `color(red)A` as

`color(blue)(A_(m xx n))`

In this case, Order of the Matrix is `color(blue)((m xx n))`

The given Matrix has ..

Rows = `2`

Columns = `3`

Hence,

Order of our Matrix is given by `(2, 3)`
