It must be more accurate tool to calculate total size of PHP variable than memory_get_usage(), but it has restrictions.

Abstract: The Laplace-domain waveform inversion is a full-waveform inversion method that recovers large-scale subsurface models. The inversion updates subsurface model parameters to minimize the ...

Abstract: It has been shown that optimizing quadratic costs for affine control systems subject to state and control constraints can be reduced to a sequence of Quadratic Programs (QPs) using Control ...
