Test Suite

Test Status Code Input and Output
1   Fail
x = [1]; y_correct = [1 1;1 1]; assert(isequal(matrix_replication(x),y_correct))

Error using repelem Replication factors must be nonnegative integer-valued scalars or vectors. Error in matrix_replication (line 2) y = repelem(x,ones(2,2)); Error in Test1 (line 3) assert(isequal(matrix_replication(x),y_correct))

2   Fail
x = [1 2;3 4]; y_correct = [1 2 1 2; 3 4 3 4; 1 2 1 2; 3 4 3 4]; assert(isequal(matrix_replication(x),y_correct))

Error using repelem With two inputs, the first argument must be a vector. Use three-input syntax for matrices. Error in matrix_replication (line 2) y = repelem(x,ones(2,2)); Error in Test2 (line 3) assert(isequal(matrix_replication(x),y_correct))

3   Fail
x = [1 2]; y_correct = [1 2 1 2; 1 2 1 2]; assert(isequal(matrix_replication(x),y_correct))

Error using repelem Replication factors must be nonnegative integer-valued scalars or vectors. Error in matrix_replication (line 2) y = repelem(x,ones(2,2)); Error in Test3 (line 3) assert(isequal(matrix_replication(x),y_correct))
