How can I iterate through two arrays at the same time without re-iterating through the parent loop. 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. Array indices must be positive integers or logical values. 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.

You overwrite A in every iteration and you are calculating the same value over and over again (not using N anywhere). 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. otherwise that's what i would have used too. Not as fast as vectorized methods if you want to check all the points, but if you don't need to evaluate most of them it can be quite a time saver. So everything is fine now.
