matlab findelement用法 在MATLAB中,`find`函数用于查找数组中满足特定条件的元素的索引,其基本语法为`ind = find(X)`。其中,`ind`为返回的索引向量,`X`为输入的数组。 当`X`为一个矩阵时,`find`函数会返回一个列向量,其中每个元素为矩阵中对应位置的非零元素的索引,从1开始计数。例如,对于矩阵`X = [1 ...
MATLAB Online에서 열기 Hello, Let's say I have 2 arrays of double, call then A and B. If both have unique entries and I want to find the position of each element of A in array B I can do: [~, pos] = ismember(A,B); ...
EDIT: to clarify, 'max' returns the index to the first occurrence when there is more than one maximal element
It works only in some cases... In the case of the same element be on the same row but diferent lines, with this code can´t be found... Any idea?Thank
I am new to python and my question might seem very badly explained because I have background in MATLAB. usually in MATLAB if we have 1000 arrays of 15*15 we define a cell or a 3D matrix which each element is a matrix with size (15*15). Now in python: (using numpy library)...
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...

two-element vector x-coordinates of the intersections, returned as a two-element vector. When the circles are tangent, the elements of the vector are equal. When the circles do not intersect or are identical, both elements are NaN. yout— y-coordinates of intersections two-element vector y...
Use the match() Function to Find the Index of an Element in R The match() function is very similar to the which() function. It returns a vector with the first index (if the element is at more than one position as in our case) of the element and is considered faster than the which...
Use the index() Function to Find the First Index of an Element in a NumPy Array In this tutorial, we will discuss how to find the first index of an element in a numpy array. Use the where() Function to Find the First Index of an Element in a NumPy Array The where() function fr...
