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.
s_rad = sin(pi)
s_deg = sind(pi)
s_rad =
s_deg =

Have you tried the functions,

Also the MAP toolbox has the functions deg2rad and rad2deg
