Whitened data #6

Closed jasonmcewen closed 8 years ago

jasonmcewen commented 9 years ago

We used to have a function purify_measurement_cftadj_whitened for first attempts to handle real data. Has this been removed or did it never make it into the repo?

I guess the plan now is to whiten data by including weighting in the l2 norm rather than the measurement operator but I just wanted to review this function.

The function never made it to the repo. As you said, what we want is to use the weighted L2 norm ball no for the constraint. We don’t want to mess up with the measurement operator.

Cool, could you just send me a copy of the function so I can take a look?

@jasonmcewen, should this be closed?

Yes, these comments were related to the old C version of the code.
