Test Suite

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]))
ans = 0.4000 0 0.7500 1.0000
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]))
ans = 0.6000 1.0000 0.2500 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)
ans = 1.0e+306 * 0.9564 0.1125 0.4661 1.5422 0.0000 1.7977 1.4010 0.9180 1.0976 0.4158 y = 1.0e+306 * 0.9564 0.1125 0.4661 1.5422 0.0000 1.7977 1.4010 0.9180 1.0976 0.4158
4   Fail
%% extrem x = diag(pascal(10)); a = -realmax/2; b = realmax/2; y = rescale_vector(x,a,b); assert(min(y)==a && max(y)==b)
Error: Assertion failed.
