lookfor:用来寻找未知的命令。例如要寻找计算反矩阵的命令,可键入 lookfor inverse,MATLAB即会列出所有和关键字inverse相关的指令。找到所需的命令後 ,即可用help进一步找出其用法。(lookfor事实上是对所有在搜寻路径下的M档案进行关键字对第一注解行的比对,详见後叙。) 将行向量转置(Transpose)後,即可得到列向量(Co...
Compute functional inverse for this trigonometric function:syms x f(x) = 1/tan(x);g = finverse(f)g(x) = atan(1/x)
When operating on vectors, poly and roots are inverse functions, such that poly(roots(p)) returns p (up to roundoff error, ordering, and scaling). p2 = poly(r) p2 = 1 -1 -6 When operating on a matrix, the poly function computes the characteristic polynomial of the matrix. The ...
