My matlab somehow in degree mode

I was trying to write some codes for signal processing. Somehow my sin,cos...commands are in degree mode. And I think those functions are somehow malfunctioned. Could anyone help me fix it?

It is not in ‘degree mode’. The sin(pi)=0, or as close as MATLAB can get to it, that in this instance is approximately eps.

Compare:

s_rad = sin(pi)

s_deg = sind(pi)

produce:

s_rad =

     122.4647e-018

s_deg =

      54.8037e-003

Thank you so much.

My pleasure!

Have you tried the functions,

sind(180)
cosd(90)

etc ?

Also the MAP toolbox has the functions deg2rad and rad2deg

Thanks, but I am not looking for alternative code. I just want to fix it.
