The code i've written just provides the same results 15 times for the 1st cells of the array. tnx @rayryeng for detected error in last answer. If there are any outputs from my_func, these are placed in outArgs, which will be the same size/dimension as A. 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. This doesn't work for arrays with different set of keys. We want to know which one is going to hit the table first and which one. https://la.mathworks.com/matlabcentral/answers/1919935-assign-a-row-vector-to-a-row-of-an-array-using-logical-indexing-to-omit-certain-values, https://la.mathworks.com/matlabcentral/answers/1919935-assign-a-row-vector-to-a-row-of-an-array-using-logical-indexing-to-omit-certain-values#answer_1181110, https://la.mathworks.com/matlabcentral/answers/1919935-assign-a-row-vector-to-a-row-of-an-array-using-logical-indexing-to-omit-certain-values#answer_1181080, https://la.mathworks.com/matlabcentral/answers/1919935-assign-a-row-vector-to-a-row-of-an-array-using-logical-indexing-to-omit-certain-values#comment_2636515, https://la.mathworks.com/matlabcentral/answers/1919935-assign-a-row-vector-to-a-row-of-an-array-using-logical-indexing-to-omit-certain-values#answer_1181105.

Iterating through a Collection, avoiding ConcurrentModificationException when removing objects in a loop. 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. Unable to complete the action because of changes made to the page. As everyone else is stating, if all he wants is each cell, liner indexing is best. In linear indexing, the elements are present in the matrix starting from the first column. As you can see, the 8th element is the number 7.

Move on to the second element in A2, 22. 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. That way you can simulate nested for loops that begin somewhere in the table and finish not at the end. I have a function, , that outputs a vector of numerical values, I also have two matrices, , the former matrix is an array of zeros, for pre-allocation, whose width is of equal length to the vector output of my function, the latter is an array of equal size and composed of logical values.I want to the iterate through the rows of Q and assign them the output of but only in the positions of G .

Making statements based on opinion; back them up with references or personal experience. How to display all products by category and sub-category wise in a single screen? If you look deeper into the other uses of size you can see that you can actually get a vector of the size of each dimension. So if your array has more then a total of 2^32 elements in it, the linear index will fail. One caveat on outputs if my_func returns outputs of different sizes and types when it operates on different elements of A, then outArgs will have to be made into a cell array. . @TalDarom I googled it before I asked and found nothing that's why I asked. Do you have any proof that verifies your claim? I think you or Andrew's approach would be easier for what I think he is trying to do. You may receive emails, depending on your.

Is A1 always evenly spaced? I can't help with the matlab notation unfortunaly. 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. 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. Let's first assume you have a function that you want to apply to each element of A (called my_func). The first one is going to be given some force and the second one will fall off the table. also, thanks for editing.

The problem is that all displayed values are the same as the value associated with the first element of "N". Caveat Emptor. Hence first iterate over the smaller dimension array and iterate over the 1-D array inside it. Other than quotes and umlaut, does " mean anything special? Then, I am writing the results in a matrix. Something like this (pardon my syntax since I have not used Matlab since college): Make this into actual Matlab-legal syntax, and I think it would do what you want. 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. Then the solution code is this one: " the latter is an array of equal size and composed of logical values. R. Ruby. I feel embarassed to answer my own question only a short while after giving it some though, but the solution is quite simple really.
