The error tells you the latex is invalid. Indeed it is, it's missing some spaces around the \mid
ylabel('$\mid H(f) \mid$ (deg/m)', 'interpreter', 'latex')

tex and latex do not permit unescaped \ before a number. If for some strange reason you want literal \ inside the string use two \\ such as 50(\\10\\0.3*\pi/10)
But I have to wonder if the intention was to form a fraction with numerator or denominator of 10. If so use \frac
