To fix the "Error using VisibleTest1 (line 4)", could you change your first line as "function b = blkavg(A,subsz)"?

*facepalm* Thank you. I feel like quite the idiot right now for not noticing that error.

Test	Status	Code Input and Output
1	Fail	A = [2 0 1 3 5 7]; subsz = [1 2]; B = [1 2 6]; assert(norm(B-blkavg(A,subsz)) < 1e-10) Error using VisibleTest1 (line 4) Too many input arguments.
2	Fail	A = [1 2 3 4 5 6 7 8 9].'; subsz = [3,1]; B = [2 5 8].'; assert(norm(B-blkavg(A,subsz)) < 1e-10) Error using VisibleTest2 (line 4) Too many input arguments.
