The datetime data type represents points in time, such as August 24, 2020, 10:50:30 a.m., and the duration data type represents lengths of time, such as 3 hours, 47 minutes, and 16 seconds. A common reason for converting dates and times to text is to append them to strings that are used as plot labels ...The NUM2STR function converts a number to the string representation of that number. This function is applied to each cell in the A array/matrix using ARRAYFUN. The 'UniformOutput' parameter is set to 0 to instruct CELLFUN to encapsulate the outputs into a cell array.You could use regexp to split the string or the function strsplit. This will give you a cell array of the values you can then to convert to a numeric array after removing and empty values. Theme. Copy. % split the string. sepVals = regexp (data {3, 1}, ' ', 'split'); % remove empties. sepVals = sepVals (~cellfun (@isempty, sepVals ));

5. If I understand you correctly, you want to extract the numbers and put them into a single column. For that you'll have to filter out the non-numbers. Cstr = cellfun (@str2num, {C {:}}, 'Uniform', 0); % # Convert strings to numbers Cnums = Cstr (cellfun (@ (v)~isempty (v), Cstr)); % # Remove empty strings. The empty cells are removed because ...

Theme. Copy. data = [z_TestImport {:}]; is probably what you're looking for. The other option is to use the CollectOutput option to textscan (set it to true). However, you still get a cell containing all the data, so you're still left with a line like. Theme. Copy. data = z_TestImport {1};

Manage Textual Information by Using Strings. str = tostring (X) converts numeric, Boolean, or enumerated data X to a string.

Convert the string array, AllSizes, to an ordinal categorical array.Use valueset to specify the values small, medium, and large, which define the categories.For an ordinal …In the third line's argument, nodes is a string and not a number anymore. Therefore you can use the cellstr-function to convert the string-array to a cell-array of …X = str2num(txt) converts a character array or string scalar to a numeric matrix. 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 to spacing around + and -operators.
