comment Replace values in a list based on conditions
It's entirely your call. I just shared what I do in these situations. :)

Boole[Thread[list > 0]] will work nicely.

comment Compilable function with the functionality of SingularValueList
Had your matrix been banded, SVD, would not be as costly to do. Your matrix is not triangular, is it?

comment Compilable function with the functionality of SingularValueList
The methods used by LAPACK (which Mathematica uses under the hood) represent the state of the art of numerical linear algebra and are the result of decades of research by many contributors. SVD has gone a long way from Golub's original Handbook implementation, and one cannot just dash off a compilable implementation so easily that will perform efficiently on matrices as large as yours. So, do first what the other comments suggested, and report back if these were not sufficient. (P.S. SVD is a very expensive algorithm in full generality, unless your matrices have exploitable structure.)

Just saw this. Haven't you already been reported to the Society for the Prevention of Cruelty to Centerfolds?

I am thankful that the faith was deserved in this case, @Oleksandr. :)

Doesn't the solver already stop exactly at the point mentioned?

comment Savitzky-Golay Filter to smooth noisy data
@Alexey, I'll add a usage example later. For now: SavitzkyGolay[n, m, Derivative -> d] corresponds to LSCoeffs[m, n, d] in Virgil's implementation in your answer.
