表达式分析+矩阵+计算器+寄存器=矩阵计算器 怎么想起来搞这个呢.. //刚看龙书兴致勃勃要搞表达式分析 这个寄存器比较简陋,26字母+4缓存,//字母不分大小写 当然,不只能算矩阵,还能算数= = 简陋的命令行如图 尚处于初步阶段,奇怪的功能们尚待加入=ω=   代码 展示一下接口吧= = //matrix.h #ifndef __MATRIX_H__ #define __MATRIX_H__ #include <vector> using std::vector; template <…

Over the years, I have collected, modified, adapted, adopted or created a number of software packages in FORTRAN. You might be able to use one of these libraries, or a routine or two from a library. The packages are at different levels of completion.…

March 16, 2016 Problem statement:Given a 2D array (matrix) named M, print all items of M in a spiral order, clockwise.For example: M  =  1   2   3   4   5       6   7   8   9  10      11  12  13  14  15      16  17  18  19  20 The clockwise spiral pr…

Atitit Data Matrix dm码的原理与特点 Datamatrix原名Datacode,由美国国际资料公司(International Data Matrix, 简称ID Matrix)于1989年发明. Datamatrix是一种矩阵式二维条码,其发展的构想是希望在较小的条码标签上存入更多的资料量.Datamatrix的最小尺寸是目前所有条码中最小的,尤其特别适用于小零件的标识,以及直接印刷在实体上. Datamatrix又可分为ECC000-140与ECC200两种类型,ECC0…

Affine Transformation是一种二维坐标到二维坐标之间的线性变换,保持二维图形的"平直性"和"平行性".仿射变换可以通过一系列的原子变换的复合来实现,包括:平移(Translation).缩放(Scale).翻转(Flip).旋转(Rotation)和错切(Shear). 在做2D图形引擎时,仿射变换是非常重要的点,图形的旋转等各种表现都需要通过仿射变换来完成,比如在显示列表树中,父节点旋转了,那么子节点在计算显示时也要叠加上父节点的变换矩阵,这是叠…

Given a n x n matrix where each of the rows and columns are sorted in ascending order, find the kth smallest element in the matrix. Note that it is the kth smallest element in the sorted order, not the kth distinct element. Example: matrix = [ [ 1, 5…

Given an integer matrix, find the length of the longest increasing path. From each cell, you can either move to four directions: left, right, up or down. You may NOT move diagonally or move outside of the boundary (i.e. wrap-around is not allowed). E…
