I ran into similar problems, so here is a very rudimentary function that I use. Do realize that it is not complete. For example, it does not output fields of a structure in a meaningful way, but that can easily be added. You can treat it as a base implementation and fit it to your needs. I want to extract values stored in myCellArray{2:14676,1} in an string array. runnning below script only returns a single string value and do not return an string array. y =. "test1".

idx = find (~cellfun (@isempty, strfind (VarNames, 'vwx'))) %find cells that match. As to indexing () vs {}: () returns a portion of the cell array. It always output a cell array, even if you only ask for one cell. You use this when you want to manipulate the container and don't care about what's in the cells.

I have created a function which takes vectors for input variables and returns a cell array for each set of inputs. The final output variable (out) seems to consist of a 2x1 cell containing two 1x5 cells. I have provided a screenshot of this below: I am just trying to figure out how to flatten the cell array (out) to be a 2x5 cell array.The corresponding character vector would be fp31 {1} Sign in to comment. If your cell array is this: access the elements using brackets: which will be a string array. Sign in to comment. Try this: c = char (fp31) % Create 2D character array.Open in MATLAB Online. hi, You can accomplish that by converting the cell to matrix first then coverting the matrix to string array. Theme. Copy.

So in that array there would be 10 elements. I tried cell2mat command, but it just puts everything in a single element, but I want each of the cell to be a seperate element, not a single element. This MATLAB function returns a string with no characters. If the size of any dimension is 0, then str is an empty array.. If the size of any dimension is negative, then strings treats it as 0.. Beyond the second dimension, strings ignores trailing dimensions with a size of 1.For example, strings(3,1,1,1) produces a 3-by-1 vector of strings with no characters.

Hi Thanks for your answer. I want a string array. I think this way may be more easy to understand: I have a cell, but have different dimensions. some has 1xN, some are 1xM. I try with strsplit and your way. those function can convert 1xM single cell to a string array. But they can't concatenate to a string array because of the inconsistent ...

I'm sure there's a way to do this but I don't know what it is. Suppose I have a vector. v = [1.02 2.03 3.04]; and I want to convert this to a cell array using a format string for each element: ' %.3f'. (3 spaces before the %.3f) The best solution is to avoid creating this cell array in the first place, and instead store the data in a string array (or as a cell array of character vectors) right from the start.Stick your char strings in another layer of cells before calling cell2struct. Instead of: X = { 'foo', 'bar' } Try: X = { {'foo'}, {'bar'} } That is, a 1-by-2 cell whose cell contents are themselves cells, not chars. Then cell2struct(X, 'name', 1) should give you a struct array with fields of cell arrays. If your existing X is a cellstr, I ...Use the function num2cell: B = num2cell(A); Works with matrices too. edited Feb 20, 2012 at 15:49. gnovice. 126k 15 257 360. answered Jan 17, 2010 at 23:52. petantik. 1,082 8 12.
