Computes the inverse cosine of the argument, but returns
the argument in degrees instead of radians (as is the case
for acos. The syntax for its use is
y = acosd(x)
Examples
The inverse cosine of sqrt(2)/2 should be 45 degrees:
--> acosd(sqrt(2)/2)
ans =
45
-->
quit
and the inverse cosine of 0.5 should be 60 degrees:
