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. So everything is fine now. The most important are: struct, matrix, and cell array. won't work if he starts using arrays with string based indexes! *L; 'W = %.2f, L = %.2f, C_I = %.6f, L_series = %.6f, R_series = %.6f\n', You may receive emails, depending on your. THe outer loop iterates over the dimension, the inner loop over the size of that dimension. Why does awk -F work for most letters, but not for the letter "t"? Ah, sorry, I asked the wrong question: Will A2 ever have elements. For example: @Edric - Of course, this is a behavior that surely would have changed in the years (and many releases) since I made that statement.

The only problem with the linear index is when they get too large. Will A2 ever have elements greater than all elements in A1? Iterating through 2 Arrays and Performing a. array(:) is not equivalent to 1 : array(1). Making statements based on opinion; back them up with references or personal experience. When referring to parts of a matrix, it's common to use the term "element", and reserve the term "cell" to refer to parts of a cell array. Summing elements of one Matrix according to the the values in another matrix into an array. MATLAB uses a 32 bit integer to store these indexes. The problem is that you are not using the index N.

To subscribe to this RSS feed, copy and paste this URL into your RSS reader. For example, lets apply a defined function to each element of a cell. Create a stacked plot of data from tbl. Conversion between the linear index and two (or higher) dimensional subscripts is accomplished with the sub2ind and ind2sub functions. If you have a function and want to apply it to each element of a given cell, one way to do that is to iterate through each element as described above and apply the function on each element, but there is another easy method in which you can use the cellfun() to apply the given function to each element of the cell. Iterating through a Collection, avoiding ConcurrentModificationException when removing objects in a loop. You first create a function handle to this function: If A is a matrix (of type double, single, etc.) In fact, the function find returns its results as a linear index. In the example above, the logical index vector. Another (probably much worse) way of looking at it for smallish arrays: % create a matrix of all combinations of A1(i)-A2(j), You may receive emails, depending on your. How can I iterate through two arrays at the same time without re-iterating through the parent loop? also, thanks for editing. For example, if we wanted to square the elements of A (yes, I know there are better ways to do this), one might do this: There are many circumstances where the linear index is more useful.
