Test Suite case 4 is a Diagonal Sparse matrix which is not a problem defined Sparse matrix and should be replaced by x = sparse(1000,100,0.01);
y_correct = 4016;.
Also, your inventive cheat detect needs to add assert(isempty(strfind(filetext, 'who'))). A re-scoring will see a new leader.
Currently Tests 4 and 5 are always pass as they lack asserts.
Enjoying the challenge.
yup, definitely need some asserts
@Richard, Thanks for your comments. I have added the assert with who and rescored all solutions.
All values at the test suite are currently wrong. Using whos in the first case, for instance, we obtain 8024 bytes and not 4016.
This problem here only focused on real sparse matrix in a 32-bit system. For real sparse matrix in a 64-bit system, we should replace 4 by 8 and 12 by 16 in the calculation. For complex sparse matrix in a 64-bit system, we should replace 4 by 8 and 12 by 24.
Wrong solution(passed due to lack of asserts in tests)
yay research! i found a paper!
whoops, this solution is a fluke. lol, guess i should have trusted the paper more.
Return the 'Size' of a String of Code
Return unique values without sorting
Convert a vector into a number
Usage of varargout
Set some matrix elements to zero
Multiply 2 numbers
Create a vector whose elements depend on the previous element
Set the array elements whose value is 13 to 0
