corrMat(List1,List2[,…[,List20]])
Computes the correlation matrix for the
augmented matrix [List1, List2, ..., List20].
cos()
µ key
cos(Value1) ⇒ value
cos(List1) ⇒ list
cos(Value1) returns the cosine of the
argument as a value.
cos(List1) returns a list of the cosines of all
elements in List1.
Note: The argument is interpreted as a
degree, gradian or radian angle, according
to the current angle mode setting. You can
use °,
G
, or
r
to override the angle mode
temporarily.
In Degree angle mode:
In Gradian angle mode:
In Radian angle mode:
cos(squareMatrix1) ⇒ squareMatrix
Returns the matrix cosine of
squareMatrix1. This is not the same as
calculating the cosine of each element.
When a scalar function f(A) operates on
squareMatrix1 (A), the result is calculated
by the algorithm:
Compute the eigenvalues (λ
i
) and
eigenvectors (V
i
) of A.
squareMatrix1 must be diagonalizable.
Also, it cannot have symbolic variables that
have not been assigned a value.
Form the matrices:
In Radian angle mode:
