Hardly an authoritative reference as it's 10 years old. +1 for showing a good example of how MATLAB breaks duck typing. For example. 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. See the code below. The result is, we can access each element in turn of a general n-d array using a single loop. Note the sequence by which the elements are displayed on the command window, and this is the sequence of the linear indexing. how to get just success message in firebase cloud message array in flutter. We want to know which one is going to hit the table first and which one. Also, you should be able to do Linear Indexing as described here. As you can see from the output, the function sin(x) is applied to each element of the cell, and the result is stored in the variable output. The problem is that you are not using the index N.

In that case the size of the array you're assigning into Q would need to be based on the number of, values in the index vector rather than the number of elements. this was exactly what I was looking for. Array indices must be positive integers or logical values. Cell arrays and matrices have numerous syntactic and semantic differences, even though both are N-dimensional data structures. otherwise that's what i would have used too.

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. yes, you are right, sorry for foolish dispute. Maybe there is a "vectorized" way to do it instead Also, if you wanted to recover the indices for some reason, you still could using these two simple commands: Indexing in 64-bit MATLAB does indeed correctly allow 64-bit subscripts. The "Range" variable i use for further processing (function parameter) within the for loop. Accelerating the pace of engineering and science. As you stated that Q and G are zero matrices generated for memoty allocation if so, and you want to to fill out the values of Q respectively with G.
