Test	Status	Code Input and Output
1	Pass	%% simple test x = [-2 -10 5 10]; a = 0; b = 1; assert(isequal(rescale_vector(x,a,b),[0.4 0 0.75 1]))
2	Pass	%% inverse test x = [-2 -10 5 10]; a = 1; b = 0; assert(isequal(rescale_vector(x,a,b),[0.6 1 0.25 0]))
3	Pass	%% extrem positive x = rand(10,1); a = realmin; b = realmax/1e2; y = rescale_vector(x,a,b) assert(min(y)==realmin & max(y)==b) y = 1.0e+306 * 0.1906 0.0000 1.6258 0.6061 1.7977 0.5052 1.4889 0.5198 1.5914 1.4523
4	Pass	%% extrem x = diag(pascal(10)); a = -realmax/2; b = realmax/2; y = rescale_vector(x,a,b); assert(min(y)==a && max(y)==b)
