Iterate Through a Matrix Using Linear Indexing in MATLAB In a matrix, there are two kinds of indexing; one is the row and column indexing in which we have to give the row and column number to access an element present in the matrix, second is the linear indexing in which we can access an element using only its linear index. Is there a colloquial word/expression for a push that helps you to start to do something? We can create a simple loop to do this. MathWorks is the leading developer of mathematical computing software for engineers and scientists.

Hence first iterate over the smaller dimension array and iterate over the 1-D array inside it. 7-5 = 2 (store this value in a separte array. Also, to expand my statement: he would still have to do a lot of other tracking of the index (using like a counter or something like that). Also, how many elements, roughly, will A1 and A2 have? menu In order to iterate a matrix using row and column indexing, you require two loops, but in the case of linear indexing, you only require one loop. Connect and share knowledge within a single location that is structured and easy to search. I was only looking for a response that returns the value at the 10, 100 and 1000th place mark on the series. In fact, the function find returns its results as a linear index. 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. Thanks for the quick response, but what this loop seems to do is tell me the entirety of the series. ;) I just ran that code too, @rayryeng i'm understanding!

I suppose I am very rusty. Use a normal for loop instead of a foreach, so that you get an explicit loop counter: If you want to use string based indexed arrays, and know that the string indexes are equal between arrays, you can stick with the foreach construct, Not the most efficient, but a demonstration of SPL's multipleIterator. Summing elements of one Matrix according to the the values in another matrix into an array. 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.
