QInterference can visualize batch of double slit experiments. It can also solve it in radial as well as Cartesian coordinates and moreover it can simulate functionality the phase-array radar with the main-bundle deflection.

einspline is a C library for the creation and evaluation of interpolating cubic basis splines (B-splines) in 1D, 2D, and 3D. It supports both uniform and nonuniform meshes, single and double precision, and real and complex data.

calculate math expression(string), for example: double ret = Cal("1+2"), ret= Cal("Pi+ln(e)+f(x,y)÷x+φ+φ0+φ1"). Features
