i have to find the index of the same value in an array,see the following example a=[1 2 3 1] i want b=[1 4] as output..how can i do this? A solution using find is this u=unique(a) n=histc(a,u) find(a==u(n>1)) but if in the a array there isn't 2 or more sam...
You can use the "cellfun()" function to apply a function to all the contents in a cell array. Further documentation on cellfun() can be found here:https://in.mathworks.com/help/matlab/ref/cellfun.html Refer to link here on finding the indices of non-...

k = find(X,n,direction) [row,col] = find(___) [row,col,v] = find(___) Description k= 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。 如果X 是向量, 则 find 返回与 x 方向相同的向量。 如果X 是多维数组, 则 find 返回结果的线性索引的列向量。 如果X 不包含非零...

k is an empty row vector or empty column vector when X is an empty array or has no nonzero elements. find uses the convention that k is an empty matrix [] when X is an empty matrix []. You can return the nonzero values in X using X(k). ...
