This is one in a series of videos covering MATLAB basics. It is meant for the new MATLAB user. This video covers how to use row and column notation to be able This MATLAB function returns a vector containing the linear indices of each nonzero Create a 6-by-6 magic square matrix with all of the odd-indexed elements Oct 27, 2017 If dir is a command, you cannot index its output by "." directly. Process it in different steps: DirList = dir(fullfile(rootpath, subfolders{i}) Otherwise, check for mismatched d - MATLAB Answers - MATLAB Central Jan 2, 2019 indexing with 0 in MATLAB?.

## I have a code but it keep saying "invalid expression. when calling a function or indexing a variable, use parentheses. otherwise check for mismatched delimiters. Follow 2,603 views (last 30 days) If you're editing this code in an editor other than the MATLAB Editor, I advise you to copy and paste it into the MATLAB Editor. If you have

However, we have repeated the element 3 index. So the computed right-hand side has element 1 and 2 copies of the updated element 3 - updated each in the same way, since that's what the code says to do. Remember I said that the MATLAB behavior is as if we placed the right-hand side into a temporary array. Indexing must follow MATLAB indexing. Function arguments must be symbolic variables, and function body must be sym expression. Can anyone help me? matlab indexing. share | improve this question. edited Nov 6 at 9:20. il_raffa. 4,694 12 12 gold badges 23 23 silver badges 30 30 bronze badges. This is the third way of indexing in MATLAB. But there is a big difference in the logic behind them. In case of usual or linear indexing we tell, which indices we do need. In case of logical indexing we use logical values to tell for each element that we need or not need it. So not indices, but logical values are used for indexing. I have talked about indexing a bunch of times in the past. Recently I have visited quite a few customers who still get tripped up a bit sometimes. So I thought I'd try again.ContentsArraysWhere People TripFunction CallsNumeric ArraysCell ArraysTablesStructuresFollow UpArraysWhat are arrays? In MATLAB, they are containers that hold information. And they are You extract contents from a cell using curly brace indexing. firstCell = myCell{1} secondCell = myCell{2} firstCell = Loren secondCell = 17 What If I Want the Contents from Multiple Cells? In that case, the cells that I want need to be capable of concatenation in MATLAB, unless I extract them each separately.

Indexing into a matrix is a means of selecting a subset of elements from the matrix. MATLAB® has several indexing styles that are not only powerful and flexible,
