find the index of 1s in logical array in matlab

To find the index of 1s in a logical array in MATLAB, you can use the find function. The find function returns the linear indices of the nonzero elements in the input array. For a logical array, the nonzero elements are those that are true, which corresponds to the value of 1.

Here's an example:

main.m
% create a logical array
A = [false true false; true false true; false true true];
 
% find the index of 1s
idx = find(A);

6 lines

The variable idx will be a column vector containing the linear indices of the elements that are true in the logical array A. You can use the ind2sub function to convert these linear indices to subscript indices if needed.
