Problem 45803. SatCom #7: Thermal Noise in a Receiver

I passed all the tests but the regex fails.

Error msg:
Error using contains First argument must be text. Error in Test4 (line 4) assert(isequal(sum(contains(s,'regexp')),y_correct))

fixed by suppressing outputs

That is weird, as un-suppressing outputs usually should not have any problem to solution.

I checked the test suite and found that the OP used importdata instead of fileread to check for regexp, which caused that particular error. I have edited the test case.

@Addison your earlier solution is rescored to be correct.
