Test Status Code Input and Output
1   Fail
x = [1 2 3; 4 5 6; 7 8 9] y = [3 5 6; 7 1 2; 4 9 8] isPerm = true; assert(isequal(isPermute(x,y),isPerm))

x = 1 2 3 4 5 6 7 8 9 y = 3 5 6 7 1 2 4 9 8 a = 9 b = 9 isPerm = logical 1

Matrix dimensions must agree. Error in isPermute (line 9) if x==2:51 Error in Test1 (line 4) assert(isequal(isPermute(x,y),isPerm))

2   Fail
x = [1 2; 4 5; 7 8]; y = x'; isPerm = true; assert(isequal(isPermute(x,y),isPerm))

a = 6 b = 6 isPerm = logical 1

Matrix dimensions must agree. Error in isPermute (line 9) if x==2:51 Error in Test2 (line 4) assert(isequal(isPermute(x,y),isPerm))

3   Pass
x = 1:50; y = randperm(50); isPerm = true; assert(isequal(isPermute(x,y),isPerm))

a = 50 b = 50 isPerm = logical 1

4   Fail
x = 2:51; y = randperm(50); isPerm = false; assert(isequal(isPermute(x,y),isPerm))

a = 50 b = 50 isPerm = logical 1 y = logical 0

Assertion failed.

5   Fail
x = [1 2 3; 4 5 6; 7 8 9] y = [3 5; 7 1; 4 9] isPerm = false; assert(isequal(isPermute(x,y),isPerm))

x = 1 2 3 4 5 6 7 8 9 y = 3 5 7 1 4 9 a = 9 b = 6 isPerm = logical 0

Matrix dimensions must agree. Error in isPermute (line 9) if x==2:51 Error in Test5 (line 4) assert(isequal(isPermute(x,y),isPerm))
