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.
