MATLAB provides several functions to search for, replace, or extract text in string arrays and character vectors. Build Pattern Expressions Regular Expressions Lookahead Assertions in Regular Expressions Tokens
error('msgString', v1, v2, ...) error('msgString') error(msgStruct) inputresult = input(prompt) (displays the prompt string on the screen, waits for input from the keyboard, evaluates any expressions in the input, and returns the result.) str = input(prompt,'s') (returns the enter...
Use the LM algorithm for regression networks with small numbers of learnable parameters, where you can process the data set in a single batch. The algorithm updates the learnable parameters W at iteration k+1 using the update step given by Wk+1=Wk+ΔWk, where ΔWk the change of the ...
上面所有函数都可以用“help funcName”或“doc funcName”命令查看帮助,参考Matlab R2012a帮助文档“MATLAB/Functions”。 当前文件夹(Current Folder)和搜索路径(Search Path): Matlab之所以强大,很重要的原因是它实现了很多数学算法,也就是有一个庞大的函数库。和其他编程语言一样,这些函数以实现文件或源文件形式存...
控制循环:包含for,ifthen,switch,while等语句 逐行执行命令 ……… end 绘图命令:将运算结果绘制出来 当然更复杂程序还需要调用子程序,或与simulink以及其他应用程序结合起来。 二、文件的编辑及MATLAB工作路径的设置 进入MATLAB的Editor/Debugger窗口来编辑程序 ...
matlab 用循环求最大值最小值f=input('input 20 numbers'); maxmun=f(1); minmun=f(1); for i=1:1:5 if f(i)>maxmun maxmun=f(i); end if f(i)<minmun minmun=f(i); end end maxmum minmun 答案显示: maxmum = 1 minmun = 1 答案 f=input('input 5 numbers'); maxnum=f(1...
function [Leader_score,Leader_pos,Convergence_curve]=WOA(SearchAgents_no,Max_iter,lb,ub,dim,fobj,handles,value) % initialize position vector and score for the leader Leader_pos=zeros(1,dim); Leader_score=inf; %change this to -inf for maximization problems ...

What can they be used for? Today I'll take you down a journey into the land of prime numbers (in MATLAB). But remember that a journey is not always about your destination, but about what you learn along the way. And so, while this will be all about primes, and specifically large ...
bins(j) is the label for the communicating class to which state j belongs. Bin values range from 1 through NumClasses. ClassStates— State names in each class cell vector of string vectors State names in each class, returned as a cell vector of length NumClasses containing string vectors. ...
