Convert cell array into matrix, but with removing the words, commas, etc

3 Ansichten (letzte 30 Tage)
I have a cell array (ED_array). Shown below. I'm trying to filter out the thin fin portion and then convert it to a matrix with just numbers.
(Cell Array)
ED_array =
3×1 cell array
{'1, thin fin, 1, 2, 7, 8, 0.1, 400.0'}
{'2, thin fin, 2, 3, 6, 7, 0.1, 400.0'}
{'3, thin fin, 3, 4, 5, 6, 0.1, 400.0'}
I have been trying to use the code below, but my output (also below) just displays empty brackets because of the 'thin fin' column. I don't want or need the thin fin portion. 'Thin fin' can change to multiple names and the clolumns can increase to any amount, so the code needs to be universal to the input file. Any help would be greatly appreciated. Thanks.
(Code)
ED_array = S(ED_2:EF_2)
Element_Data = cell2mat(cellfun(@str2num,ED_array,'uniform',0))
(Output)
Element_Data =
[]

Where does the cell array come from? If it's from a file import then the simplest thing is to fix the import. It is very likely that you could import the data in the exact format that you want with just a few lines of code.
Most likely something like:
filename = 'C:\somewhere\somefile.ext'
opts = detectImportOptions(filename);
opts.SelectedVariableNames = opts.VariableNames([1, 3:end]); %tell matlab to skip 2nd variable
Element_Data = readmatrix(filename, opts)

It originates from a .txt file that has a lot of other information in it. I was able to filter through everything except this one array because of the words in the matrix. I see what your recommending though, thanks for the help!
