You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. 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. Hardly an authoritative reference as it's 10 years old. The problem is that all displayed values are the same as the value associated with the first element of "N". You can use linear indexing to access each element. %The index has to have two terms removed because it starts with 1 and 1 already, %The current term in the series is a summation of the previous two terms, %Each term must by iterated upwards by an index of one, %The term that previously was second is now referred to as next. Let's first assume you have a function that you want to apply to each element of A (called my_func). However, if you don't need to know what index you are at, you are probably better off using arrayfun(). How far does travel insurance cover stretch? Unable to complete the action because of changes made to the page. The problem is that all displayed values are the same as the value associated with the first element of "N".

Depending on how you want to manipulate the entries you have to use both indexes accordingly. my link was kinda convoluted and just would not work right using the usual linking way. How do I efficiently iterate over each entry in a Java Map? In the example above, the logical index vector. 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. offers. For example, lets apply a defined function to each element of a cell. Donald, regarding your new "Answer", you can do it like this: Use a for loop to calculate the elements o. for the maximum value in N. Scala. W = 0.80, L = 4.50, C_I = 0.000000, L_series = 0.000001, R_series = 0.095607 A = (Array (1,1)*Z)/Array (1,2); This line doesn't change, so you will get the same output 15 times. For example, D = find (Y) remits a vector containing the linear indices of each nonzero element in array Y. 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. A Computer Science portal for geeks. 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.
