I have completed my program about three months ago and it was working perfectly. My laptop was broken one month ago, so I have loaded Matlab R2013a again. Today, I got this error:
Undefined function 'deg2rad' for input arguments of type 'double'
Related line is:
rb = rp*cos(deg2rad(pre_ang));
where pre_ang is an input value, rb and rp are calculated by program.
Why is this happening now although it was not a problem before?
Thanks to contributers.
