The end answer of logical array should be [0 0 0 0 0 1 1 1]. The loop should run until no values is < f_min.
WebWhen we index an array with a logical variable, Matlab is using find to locate all the true elements and convert them to indices. So for instance, if we create a 5x5 array of random integers from 1 to 50: A=randi (50,5,5); %look this command up we could grab a sub-block of it by using indices... A (1:2,3:4) %remember this? ans = 22 24 8 15 WebJun 14, 2024 · One way is to do the following: mask = [s.z] > 0; s_concatenated = [s.x; s.y; s.z]'; mask_applied2struct = s_concatenated (mask); Now my Question is whether there is a way to apply a logical mask to a struct data type in Matlab? Perhaps in following Fashion, e.g.: mask_applied2struct = s ( [s.z] > 0) or mask_applied2struct = [s] ( [s.z] > 0)
