% This is the magnetization curve given as a table
% in Problem 9-14.  The first column is the 
% magnetimotive force in ampere-turns, and the second 
% column is the open-circuit terminal voltage in volts 
% at a speed of 900 r/min.  The data will be loaded into 
% an N x 2 array named prob9_14, with the first column 
% containing the mmf and the second column containing 
% the open-circuit voltage. MATLAB function "interp1" 
% can be used to recover a value from this curve.  
% (Be sure to use the 'spline' option to get a smooth
% interpolation between these sparse points.)
