Indexing is one of the exceptions where they are treated differently. Hardly an authoritative reference as it's 10 years old. @Danon second example works assuming arrays share length and element order. Hence first iterate over the smaller dimension array and iterate over the 1-D array inside it. How to iterate over elements of a Multidimensional array? You can save data to a file like this: If your data has been saved and you want to save it to a file, you can do that by using Matlab's function SaveDataToFile. for instant: , that outputs a vector of numerical values, I also have two matrices, , the former matrix is an array of zeros, for pre-allocation, whose width is of equal length to the vector output of my function, the latter is an array of equal size and composed of logical values. W = 0.65, L = 6.00, C_I = 0.000000, L_series = 0.000002, R_series = 0.156893 A nested loop would look like this: Theme Copy [row,col] = size (B); for N = 1:col for M = 1:row A = (B (M,N)*Z)/B (1,2); disp (A) end end The first loop will start at column 1, then the second loop goes through all rows. Reload the page to see its updated state. No, A2 will not be less than A1. We can see the order the elements are stored in memory by unrolling the array into a vector. second array $b = array(1,2,3,4,5); The result that I would like through iterating through both is having the looping process going through the same values to produce a result like, I tried to do it this way below but it didn't work , it keeps going through the first loop again. At each dimmension we have as many digits as the lenght of the dimmension. Array indices must be positive integers or logical values. Theme Copy N= [10 100 1000]; first=1; second=1; for i=1: (N-2) %The index has to have two terms removed because it starts with 1 and 1 already next=first+second; %The current term in the series is a summation of the previous two terms sites are not optimized for visits from your location.
