Output argument "tf" (and maybe others) not assigned during call to "isFibMat". Error in Test1 (line 3) assert(isequal(isFibMat(x),tf))

2   Pass
x = [1 0;1 1]; tf = false; assert(isequal(isFibMat(x),tf)) clear all;

3   Fail
x = [0 1;1 1]^40; tf = true; assert(isequal(isFibMat(x),tf)) clear all;

Output argument "tf" (and maybe others) not assigned during call to "isFibMat". Error in Test3 (line 3) assert(isequal(isFibMat(x),tf))

4   Pass
x = [0 1;1 1]^40+1; tf = false; assert(isequal(isFibMat(x),tf)) clear all;

5   Fail
x = [0 1;1 1]^17; tf = true; assert(isequal(isFibMat(x),tf)) clear all;

Output argument "tf" (and maybe others) not assigned during call to "isFibMat". Error in Test5 (line 3) assert(isequal(isFibMat(x),tf))

6   Pass
x = [0 1;1 1]^17-5; tf = false; assert(isequal(isFibMat(x),tf)) clear all;

7   Pass

8   Pass
x = [0 0 1;0 1 1]; tf = false; assert(isequal(isFibMat(x),tf)) clear all;

9   Pass
x = [[0 1;1 1]^3 [5; 8]]; tf = false; assert(isequal(isFibMat(x),tf)) clear all;

10   Fail
x = uint8([0 1; 1 1]^5); tf = true; assert(isequal(isFibMat(x),tf)) clear all;

Output argument "tf" (and maybe others) not assigned during call to "isFibMat". Error in Test10 (line 3) assert(isequal(isFibMat(x),tf))

11   Pass
x = -([0 1; 1 1]^5); tf = false; assert(isequal(isFibMat(x),tf)) clear all;

12   Pass
x = [0 1; 1 1]^5; x(2) = nan; tf = false; assert(isequal(isFibMat(x),tf)) clear all;

13   Pass
x = [4 7;7 11]; tf = false; assert(isequal(isFibMat(x),tf)) clear all;

14   Fail
for ii = 1:55 assert(true==isFibMat([0 1;1 1]^ii)) end

Output argument "tf" (and maybe others) not assigned during call to "isFibMat". Error in Test14 (line 2) assert(true==isFibMat([0 1;1 1]^ii))
