A Randomized Multivariate Matrix Pencil Method for Superresolution Microscopy
Martin Ehler, Stefan Kunis, Thomas Peter +1
The matrix pencil method is an eigenvalue based approach for the parameter identification of sparse exponential sums. We derive a reconstruction algorithm for multivariate exponent…
