You overwrite A in every iteration and you are calculating the same value over and over again (not using N anywhere). Other MathWorks country There is no shortest path between any pair of vertices , which form part of a negative cycle, because path-lengths from to can be arbitrarily small (negative). The timing information that this post has referenced is incorrect and inaccurate due to a fundamental typo that was made (see comments stream below as well as the edit history - specifically look at the first version of this answer). Check this link for more information about the cellfun(). The code i've written just provides the same results 15 times for the 1st cells of the array.

Launching the CI/CD and R Collectives and community editing features for How to iterate over a column vector in Matlab? For example. Not the answer you're looking for? In conjunction with numel and size, this can let you do stuff like the following, which creates an N-dimensional array, and then sets all the elements on the "diagonal" to be 1. W = 0.65, L = 3.00, C_I = 0.000000, L_series = 0.000001, R_series = 0.078446 No, A2 will not be less than A1.

Connect and share knowledge within a single location that is structured and easy to search. Why did the Soviets not shoot down US spy satellites during the Cold War? That way you can simulate nested for loops that begin somewhere in the table and finish not at the end. 24,961 Solution 1. Scala. So if your array has more then a total of 2^32 elements in it, the linear index will fail. Could you please complete the code line within the for loop? In linear indexing, the elements are present in the matrix starting from the first column. So you can use it on structures, cell arrays, etc. that gives the following output after execution: We can see how the totalSalary variable is added with each of the value of the elements of the salaries array by iterating the for loop to retrieve the sum of the array elements that is the total salary of all the employees.

Thanks for the quick response, but what this loop seems to do is tell me the entirety of the series. @TalDarom - I did. Hi, I would like to write a code whith two arrays as inputs: W_C and L_C I want to calculate some formulas for each value. We can create a simple loop to do this. *L_C; epsilon_re=0.5*(epsilon_r+1)+0.5*(epsilon_r-1)*(1+12*(H./W)).^(-0.5); C_I=0.5*epsilon_o*(epsilon_r+1)*(5.5.
