fixed QR solver to work with non-square matrices 14th Feb 2015: merged from Frograms branch investigated and documented fix for 'can't obtain lastUpdateError' jna linking issue 17th Dec 2014: Added native library inside the jar, with automatic extraction, and setting of the jna.library.path ...
As we have seen, Mata works with real numbers: : 2+3 5 Mata also understands complex numbers; you write the imaginary part by suffixing a lowercase i: : 1+2i + 4-1i 5+1i For imaginary numbers, you can omit the real part: : 1+2i - 2i 1 Whether a number is real...

The solver performs a frequency domain analysis using a numerical method that divides the computational area of a scatterer into a certain number of meshing domains and then estimates the current distribution (and then the radiated fields) over each segment area. With the integral equation solver, ...
We present a novel a,v-q hybrid method for solving large-scale time-harmonic eddy-current problems. This method combines a hybrid unsymmetric formulation based on the cell method and the boundary element method with a hierarchical matrix-compression tech

As an effective CMI problem solver, the Newton iterative method is deeply studied [5]. However, with the increase of matrix dimension, the Newton iterative method cannot deal with the sharply increasing computational workload. Generally, the computational complexity of numerical iterative method is O...
All logic expressions in the above are implemented using the indicator constraint option of the CPLEX solver incorporated in the General Algebraic Modeling System (GAMS) [14]. Once all the elements of 𝑐c are calculated using Equations (27)−(29), they can be entered into Equation (12),...
