### Test Suite

Test Status Code Input and Output
1   Fail
a = [6 5 4;3 6 5;2 3 6]; y_correct = 1; assert(isequal(toeplitzcheck(a),y_correct))

Index in position 1 exceeds array bounds (must not exceed 1). Error in toeplitzcheck (line 7) working_matrix = working_matrix - diagonal(element*ones(sizea-diagonal),diagonal) Error in Test1 (line 3) assert(isequal(toeplitzcheck(a),y_correct))

2   Fail
a =[3 2 1 0;4 3 2 1;5 4 3 2;6 5 4 3]; y_correct = 1; assert(isequal(toeplitzcheck(a),y_correct))

Index in position 1 exceeds array bounds (must not exceed 1). Error in toeplitzcheck (line 7) working_matrix = working_matrix - diagonal(element*ones(sizea-diagonal),diagonal) Error in Test2 (line 3) assert(isequal(toeplitzcheck(a),y_correct))

3   Fail
a =[1 2 3;4 5 6;7 8 9]; y_correct = 0; assert(isequal(toeplitzcheck(a),y_correct))

Index in position 1 exceeds array bounds (must not exceed 1). Error in toeplitzcheck (line 7) working_matrix = working_matrix - diagonal(element*ones(sizea-diagonal),diagonal) Error in Test3 (line 3) assert(isequal(toeplitzcheck(a),y_correct))

4   Fail
a =[2 0 7 8 9;3 2 0 7 8;6 3 2 0 7;4 6 3 2 0;1 4 6 3 2]; y_correct = 1; assert(isequal(toeplitzcheck(a),y_correct))

Index in position 1 is invalid. Array indices must be positive integers or logical values. Error in toeplitzcheck (line 7) working_matrix = working_matrix - diagonal(element*ones(sizea-diagonal),diagonal) Error in Test4 (line 3) assert(isequal(toeplitzcheck(a),y_correct))

5   Fail
a =[2 0 5 8 7;3 1 0 2 8;6 4 2 0 3;4 6 1 2 0;7 4 8 3 9]; y_correct = 0; assert(isequal(toeplitzcheck(a),y_correct))

Index in position 1 is invalid. Array indices must be positive integers or logical values. Error in toeplitzcheck (line 7) working_matrix = working_matrix - diagonal(element*ones(sizea-diagonal),diagonal) Error in Test5 (line 3) assert(isequal(toeplitzcheck(a),y_correct))
