[row,col,V] = find():返回包含非零元素的向量 V 现在让我们看看如何在示例的帮助下使用find()函数查找数组中任何元素的索引。 找到(x) find(X) 返回一个向量,其中包含 数组 X 中每个非零元素的线性索引。 示例1: MATLAB % MATLAB code for find an index of any % element in an ar
Given two array Idx_of_pt and P, I'd like to find all the row element in P from Idx_of_pt Idx_of_pt=[1 2 3;4 6 7;2 3 5]; P=[-0.03 0.12 0.04 -0.94 0.12 0.01 -0.06 0.15 0.037 -0.22 0.13 0.02 -0.26 0.12 0.07
k = find(X) k = find(X,n) k = find(X,n,direction) [row,col] = find(___) [row,col,v] = find(___)Description k = find(X) returns a vector containing the linear indices of each nonzero element in array X. If X is a vector, then find returns a vector with the same or...

k = find(X) returns a vector containing the linear indices of each nonzero element in array X. If X is a vector, then find returns a vector with the same orientation as X. If X is a multidimensional array, then find returns a column vector of the linear indices of the result. examp...
Open in MATLAB Online Given two vectors A and B, find the index, idx into A of the element of B so that A(idx)=B. Now I know there must be many ways it can be done, but is there a one-liner? For example if ThemeCopy A=[3 4 5 6 7]; B=[6 4 7]; then T...
IfAis a character vector of typechar, thennumelreturns the number of characters. However, ifAis a string scalar,numelreturns1because it is a single element of a string array. For example, compare the output ofnumelfor a character vector and string: ...
