cosê(
squareMatrix1
) ⇒
squareMatrix
Returns the matrix inverse cosine of
squareMatrix1
.
This is
not
the same as calculating the inverse
cosine of each element. For information about the
calculation method, refer to
cos().
squareMatrix1
must be diagonalizable. The result
always contains floating-point numbers.
In Radian angle mode and Rectangular
complex format mode:
