rad2deg — Convert angles from radians to degrees.
d = rad2deg(r) converts each angle in r from radians to degrees using r*180/pi.
How rad2deg works
- Operates element-wise on scalars, vectors, matrices, and N-D tensors.
- Integer and logical inputs are promoted to double precision before conversion.
- Complex inputs are scaled component-wise, matching ordinary multiplication by
180/pi. - Output shape matches the input shape.
- String inputs are unsupported and raise a builtin-scoped error.
Examples
Converting a scalar angle
d = rad2deg(pi)Expected output:
d = 180Converting a vector of angles
angles = [0 pi/6 pi/4 pi/3 pi/2];
d = rad2deg(angles)Expected output:
d = [0 30 45 60 90]FAQ
Is rad2deg(x) equivalent to x*180/pi?⌄
Yes. The builtin exists for readability and MATLAB compatibility.
Does rad2deg preserve array shape?⌄
Yes. Each element is converted independently and the original shape is preserved.
