太阳风（低密度等离子体）在带电平板周围的粒子密度、电势的PIC法模拟。(The code simulates flow of solar wind (low density plasma) over a charged plate. )

图像处理实验报告，实验内容：用matlab实现图像增强，包括灰度变换，滤波，色彩增强(image processing experiments, experimental content : Matlab image enhancement, including gray-scale transformation, filtering, enhanced color)

SparseArrays map integers to Objects. Unlike a normal array of Objects, there can be gaps in the indices. It is intended to be more efficient than using a HashMap to map Integers to Objects.
