The input can include spaces, commas, and semicolons to indicate separate elements. If str2num cannot parse the input as numeric values, then it returns an empty matrix. The str2num function does not convert cell arrays or nonscalar string arrays, and is sensitive ...I'll post it here for anyone interested in converting arbitrary things to string, and generally having more control over how that conversion is done. It supports empties, logicals, chars, function handles, numerics, cells, struct (arrays), and user-defined classes (sparse arrays in the next update).It depends how you want to split it. For your case (before your edit with square brackets) it's very easy: A = ['12345'; '67890'; '12345'] B = A(:,1:3) C = A(:,4:end) For more complicated cases, have a look at strsplit (a quite new function, otherwise available at File Exchange) Actually you mentioned you'd have a cell array, and also if your ...Or use a more efficient solution on this as suggested by @Luis -. split1 = regexp(str_cellarr, ':', 'split') After this you can employ two approaches.

Syntax. A = cell2mat(C) Description. example. A = cell2mat(C) converts a cell array into an ordinary array. The elements of the cell array must all contain the same data type, and the resulting array is of that data type. The contents of C must support concatenation into an N-dimensional rectangle. Otherwise, the results are undefined.Update code that makes use of strjoin to use join instead. strjoin returns a character vector if the input is a cell array of character vectors and returns a string scalar if the input is a string array. join returns a text scalar of the same type as the input. For example: 'one two three'. {'one two three'} 'one two three'.I needed some categorical data in my output table, which required a slightly different solution, because the cells with strings were outputtinga logical array, rather than a single value for missing.

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 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.

If all of your structures in your cell array have the same fields ('x', 'y', and 's') then you can store mylist as a structure array instead of a cell array.You can convert mylist like so:. mylist = [mylist{:}]; Now, if all your fields 's' also contain structures with the same fields in them, you can collect them all together in the same way, then check your field …

data{1} = 'hello'; %// assign a string as contents of the cell. The notation data(1) refers to the cell itself, not to its contents. So you could also use (but it's unnecessarily cumbersome here): data(1) = {'hello'}; %// assign a cell to a cell. More information about indexing into cell arrays can be found here.

C(1:10) = {""} % Array of empty string C(1:10) = {[]} % Array of empty double, same as cell(1,10) But be careful with scalersIn fact I would like to save the whole of cell array "features_score" in to *xls/csv file, in which first column of file is for strings and the second column is numeric values. beside your solution, there is another problem that some strings do not fit in one row and take 2 rows...Dec 9, 2013 · y{1}(2) ans =. G. Also keep in mind that the char function can convert a cell array of strings into a 2D character array by vertically concatenating the strings while padding with white space as necessary: S = char(C), when C is a cell array of strings, places each element of C into the rows of the character array S. Use CELLSTR to convert back. Assume I have A that is a 64x1 cell array.
