👉 Learn how to solve problems with rectangles. A rectangle is a parallelogram with each of the angles a right angle. Some of the properties of rectangles are: each pair of opposite sides are equal, ...

Learn how to eliminate the parameter in a parametric equation. A parametric equation is a set of equations that express a set of quantities as explicit functions of a number of independent variables, ...

Abstract: To improve the estimation accuracy of two-dimensional (2D) direction-of-arrival (DOA) of uniform rectangular array, and increase the degrees of freedom of the array, this paper proposes a ...

Abstract: Most existing near-field (NF) source localization methods are based on uniform/sparse symmetric linear arrays. But planar arrays will be more common in the future. In this paper, we propose ...

// Useful for e.g. packing rectangular textures into an atlas. // Does not do rotation. // Not necessarily the awesomest packing method, but better than // the totally naive one in stb_truetype (which ...
