Is that something close to what you are looking for? ), the command A && B does the following:. looks like you have an end before all your elseif's that shouldn't be there. I want to display the values when f=0, when v is closest to 0, and when h is closest to 0. Next, this chaging value and the constant variables are used to find a model that best represents the data. I have two for loops I want to graph continuously. This can be calculated to give the below result: As we have taken i=5, then i2(i + 1 ) = 52 * 6 = 150 This is what you get in MATLAB: a = 0; for m = 1:5 for n = 1:5 a = a + m + n… The way the code works is there is a for loop that iterates through a set of sigma_sub pre defined values, picks one postion of the iteration and sets sigma_sub to that value. 0. The FOR loop is used when the number of iterations that a set of instructions is to be executed is known. % iterates through predefined values, picks position, assigns sigma value. outputData = zeros(length(sigmasub_val), 2); % <--- create an output array for sigmasub,numComponents. This is the 'safest' and simplest way of looping through two separate loops, and is generally your solution here. I have a condition in the innermost for loop. It requires one to understand how MATLAB stores elements in memory when creating an array. 0 Comments. https://www.mathworks.com/matlabcentral/answers/529633-nested-for-loop-combine-two-for-loops#answer_435648, https://www.mathworks.com/matlabcentral/answers/529633-nested-for-loop-combine-two-for-loops#comment_855883. JESUS DAVID ARIZA ROYETH on … That aside, because you are looking to loop through two separate arrays, you really need two separate loops. So after seeing this answer I solved one issue, that i update the graph using update. The other for loop runs 4 tmes through different models to find the best one, and outputs the value of the numComponents of the best model for the given sigma_sub value and constants.

Choose a web site to get translated content where available and see local events and offers. And the plot was supposed to be inside the for loop. You may also want to consider what happens if x is Not-a-Number, better known as NaN. So far, I am varying only the sigma_sub of the sub (smaller) population, while keeping the other variables constant. If you've preallocated delta_x and delta_y, having 0 as the last element in x won't leave those two arrays shorter than you expect. Elizabeth - perhaps you can combine the two as follows. Do i make myself clear? So for every value of sigma_sub, have 4 models be tested on each value, and output the best model. You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance.

There are also nested loops, which allow using either for or while loops within a loop. It just takes a very very long time to run. That's because if all your mat files have variables of the same name in them - data - then they keep overwriting each other and only the last data survives. I needed to plot graph of frames Vs pixel difference. id = [ 1 3; 2 6; 3 2; 4 5; 5 1; 6 4; 7 7]; I will get two new_ids by sorting its column.
