Study of non - self - adjoint variational problem in low - frequency eddy current electromagnetic field 低频涡流电磁场非自伴变分问题的研究
It interprets image editing as a variational problem concerning the adaptive adjustments to the zero - and first - derivatives of the images which correspond to the color and gradient items 模型将图像编辑问题理解为同时考虑图像的零阶图像的颜色和一阶图像的梯度变化的自适应调整问题。
As we know , fem is a method that transforms differential equations with boundary conditions into a variational problem , and then performs a numerical analysis to get the result . the thesis gives the realization of fem detailedly 有限元是将微分方程转化为变分问题后进行数值求解的数值方法,本文详尽地给出了有限元的实现过程。
