load metal.m					% Load the data from file
metal							% Verify input data
T=metal(:,1);  I=metal(:,2);			% Separate into two columns
options=optimset( 'TolX', 1e-10);		% Tolerance for p
pm=fminbnd( @ssq1, 0, 1, options, T, I)	% p at minimum
ssqmin=ssq1( pm, T, I);			% Minimum value of ssq1
n=length(T)					% Number of elements
sdev=sqrt( ssqmin/(n-1))			% Standard deviation
