摘要： Subscript. indices must either be real positive integers or logicals中文解释：下标索引必须是正整数类型或者逻辑类型出错原因：在访问矩阵（包括向量、二维矩阵、多维数组，下同）的过程中，下标索引要么从 0 开始，要么出现了负数。注：解决办法：自己调试一下程序，把下标为 0 或者负数的地方修正。举例：【错误代码】：代码:for s = 0:0.2:2a(s) = 4 * s - 1;end【正确代码】：代码:for s = 1:10a(s) = 4 * s - 1;end当然，这样的赋值使用循环是低效的，因此不提倡Undefined 阅读全文

摘要： 奥地利符号计算研究所（Research Institute for Symbolic Computation，简称RISC）的Christoph Koutschan博士在自己的页面上发布了一篇文章，提到他做了一个调查，参与者大多数是计算机科学家，他请这些科学家投票选出最重要的算法，以下是这次调查的结果，按照英文名称字母顺序排序。A* 搜索算法——图形搜索算法，从给定起点到给定终点计算出路径。其中使用了一种启发式的估算，为每个节点估算通过该节点的最佳路径，并以之为各个地点排定次序。算法以得到的次序访问这些节点。因此，A*搜索算法是最佳优先搜索的范例。集束搜索（又名定向搜索，Beam Search 阅读全文
