So far, I am varying only the sigma_sub of the sub (smaller) population, while keeping the other variables constant. You may also want to consider what happens if x is Not-a-Number, better known as NaN. 0 Comments. outputData = zeros(length(sigmasub_val), 2); % <--- create an output array for sigmasub,numComponents. If you look at the first set of loops you have you will notice there is one for a, and one for b. sigmasub_pos = randi(length(sigmasub_val)); Next, this chaging value and the constant variables are used to find a model that best represents the data. 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.

Each variable has one column of data in varying lengths. y = sigma_main. I want to get 2 results from each of the new_id respectively. And the plot was supposed to be inside the for loop. Try with a temporal variable in between, if it does not work, paste the error and the value of, You may receive emails, depending on your. This means that I will have in total 4 results. I am writing code to identify two populations of cells with varying sigma, mu, and quanitities.

Return True, if both A and B are True, return False otherwise.. The code above gives me two sets of array,result{1} and result{2}. 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. 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. My problem here is the output only shows me the loop when col=2, it overwrite the output for col=1, what can I do in order for me to keep both of the results for col=1 and 2? 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. As we saw before, a nested for loop is a loop within a loop. ... how to exit from two nested for loop in matlab. 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.

Find the treasures in MATLAB Central and discover how the community can help you! Hence, it is used to execute code repeatedly as long as a certain condition is met. MATLAB uses for loops and while loops. So for every value of sigma_sub, have 4 models be tested on each value, and output the best model. If you don't understand the language, do not edit the code. I tried it, but I get separate figures e.g. Show Hide all comments. Learn more about combine, for loop, array Next, this chaging value and the constant variables are used to find a model that best represents the data. Everything else seems to be working as I want it.

The syntax of a for loop in MATLAB is −. RAN 20 – Estimations.xlsx, RAN 23 – Estimations.xlsx, RAN120 – Estimations.xlsx. What you want is the following: Go from 0 to 180 in steps of 1 AND then go from 180 to -180 in steps of -1. a = 0; for m = 1:5 for n = 1:5 a = a+m+n; end end But when we look at the above loop structure in Mathematics term then, it seems that we are calculating the sum as m=1∑5 n=1∑5 (m + n). Other MathWorks country sites are not optimized for visits from your location. Other MathWorks country sites are not optimized for visits from your location. The FOR loop is used when the number of iterations that a set of instructions is to be executed is known. You were not very clear in your explanation, but I think you want this: % pre-allocation of 2x2 cell array to hold data, whose columns contain the result of your first loop, I tested it in Matlab 2012a and it works. 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… Following section shows few examples to illustrate the concept.
