Find indices and values of nonzero elements. collapse all in page. Syntax. 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.
Use nonzeros, nnz, and find to locate and count nonzero matrix elements. Create a 10-by-10 random sparse matrix with 7% density of nonzeros. A = sprand(10,10,0.07); Use nonzeros to find the values of the nonzero elements. v = nonzeros(A) v = 7×1. 0.9595.
any(A) returns logical 1 (true) if any of the elements of A is a nonzero number or is logical 1, and returns logical 0 (false) if all the elements are zero. If A is a nonempty, nonvector matrix, then B = any(A) treats the columns of A as vectors, returning a row vector of logical 1 s and 0 s.
16 lip 2013 · To remove zeros (or any individual number): X6cell{i}=X6(i,X6(i,:)~=0); To remove any amount of numbers, use ~ismember: X6cell{i}=X6(i,~ismember(X6(i,:),discard_values)); To chain these rules (introducing a new variable just for clarity), use &: indices_to_keep= ~ismember(X6(i,:),discard_values) & ~isnan(X6(i,:));
10 paź 2023 · MATLAB provides a built−in function "find" which enable us to find the indices and values of non−zero elements in a given array or matrix. However, in MATLAB, we can also find the values and indices of non-zero element using loop mechanism i.e., without using the "find" function.
Accepted Answer: Guillaume. Hey, I would like to find the non-zero cells plus the zeros that has no zeros before or after them. For example in the array [0 1 2 2 2 0 0 4 5 0 3 0 0 0 5] I'll get the indexes: 1,2,3,4,5,8,9,10,11,15. Thanks!
I have a matrix of 1x1177 and I wanted to display all the nonzero values with the array and the location of them. I am able to get the location of them using: find (matrixOne) But I also need the values to be displayed.
