Description

The formula 'Covariance' returns the covariance of two matrices over the rows or the columns of those matrices, depending on the chosen dimension.

Parameters

Dimension:

The dimension to take the covariance over. 1 means downwards (over rows), 2 means rightwards (over columns).

Matrix1:

The first matrix you want to know the covariance of.

Matrix2:

The second matrix you want to know the covariance of.

Example

Description

In the following example the formula 'Covariance' is used to take the covariance over the columns.

Values parameters

Matrix1:

Column1 Column2 Column3 Column4 Column5
1 2 3 4 5

Matrix2:

Column1 Column2 Column3 Column4 Column5
1 9 4 2 8

Dimension: 2

Result

Outcome:

1,4

As you see the result is the covariance of the rows of the two matrices.
