If the statement isn't true when you try to run the loop for the first time it will not execute at all. In this case the loop will continue to loop while index satisfies the logical statement here. This type of loop will ALWAYS, and I repeat ALWAYS execute at least once. In the above example the loop will continue to loop until the index value index becomes greater than or equal to someValue at the end of the current iteration of the loop. Many times you'll see this done with a while loop or a do while combo.Ī few examples are as follows: index = 0 Generally this isn't the best idea when you're using a for loop as the value of your indexing variable will be changed by the loop as well as by you within the loop. Secondly here you can modify the value within the loop itself. Namely trying to index out of bounds of the matrix or potentially going negative. Follow 18 views (last 30 days) Show older comments. A for loop that finds multiples of certain numbers in a given range. I am trying to create a for loop that finds all values in the range 1,100 that are also multiple of 3 or 5 and save these in a row vector labeled M1. When you combine this with row vectors, then the result would be to implicitly expand to two dimensions. Learn more about for loop, multiple, mod 3 or 5 MATLAB. ' there: it is transposing the 0:60 from a row vector into a column vector. You just have to be aware of potential indexing issues that can arrise. theta (0:60).' and remember to use cosd () and sind () Notice the. Obviously you can replace the value between the two : to be a step size that you want. It would look like this: for index = someValue:-1:1 You can also do every 4th index while going backwards for index = someValue:-4:1. The loop runs until the terminate condition is met. In the loop, you can increment the value of x and update your y array. In this case you start at the 'end' and move to the beginning. Your terminate condition, which is y(m+1) > 11, is checked at the beginning of each iteration of the while loop. ![]() Yet another modfication is traversing backwards. All you have to do is: for index = 2:3:someValue The 3 here tells the loop that it should add 3 to the index at the end of each loop iteration until you get to (or surpass) someValue. You can modify this as well though! Let's say you want every 3rd index starting with the 2nd position in the matrix. for ii in range(len(resps)): thisOri orisii thisResp respsii thisRT. Many times it's simply the last index value of a matrix you're wanting to traverse. In many languages for is used for looping over some numbers, which you then. SomeValue can really be anything that is greater than 1 in this case. The general syntax is for index = 1:someValue I will also open this up for community wiki so others can just easily edit this as well. ![]() ![]() There are two main ways that I can think of off the top of my head.
