Test Suite

Test Status Code Input and Output
1   Fail
a = 2*3.^(1:3); b = 3*4.^(0:5); vec = [a b]; output = b; test = gSeries(vec); assert(isequal(test,output));

y = 6.0000 3.0000 1.5000 0.7500 0.3750 0.1875 0.0938 0.0469 0.0234

Assertion failed.

2   Fail
a = ones(1,50); b = 3*4.^(1:5); vec = [a b]; output = a; test = gSeries(vec); assert(isequal(test,output));

Index exceeds the number of array elements (6). Error in gSeries (line 10) m = temp2(i); Error in Test2 (line 5) test = gSeries(vec);

3   Fail
a = ones(1,50); b = randi(5,[1 10]); p = randperm(60); vec = [a b]; vec = vec(p); output = nonzeros(vec==1)'; test = gSeries(vec); assert(isequal(test,output));

Index exceeds the number of array elements (4). Error in gSeries (line 10) m = temp2(i); Error in Test3 (line 7) test = gSeries(vec);

4   Fail
a = 2.^(1:15); b = 3.^(1:10); c = 5.^(1:10); vec = [a b c]; p = randperm(35); vec = vec(p); output = a; test = gSeries(vec); assert(isequal(test,output));
