Find the nonzero elements in a 4-by-2-by-3 array. Specify two outputs, row and col, to return the row and column subscripts of the nonzero elements. When the input is a multidimensional array (N > 2), find returns col as a linear index over the N-1 trailing dimensions of X.
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.
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.
2 sie 2016 · You can use any to find any rows that have non-zeros and then negate the result. We use the second input to specify that we want to apply the operation across the columns (the 2nd dimension). row_has_all_zeros = ~any(data, 2) If you want the indices instead of the logical array, just apply find to the result: indices = find(row_has_all_zeros);
14 lut 2024 · The find() function in MATLAB is used to locate the indices of non-zero elements in an array or matrix. It is a versatile function that can be applied to vectors, matrices, and multidimensional arrays. The syntax of the find() function is flexible, accommodating different scenarios: indices = find(X)

Hello, For example I have a vector A = [ 0 0 0 0 0 0 0 1 1 1 1 0 0 0 0 0 0 0]. And I do find(A,2)-2, so I have the 2 zeros before the first one. However, how can I get the 5 zeros before the f...
