Edited: Cedric …my_cell = {'Hello World'} class(my_cell) ans = cell We can get the string out of it simply by using the {:} operator on it directly. class(my_cell{:}) ans = char Note that we can use the expression mycell{:} anywhere we would use a normal string.To pass data from a string array to such functions, use the cellstr function to convert the string array to a cell array of character vectors. Create a string array. You can create strings using double quotes. A = [ "Past", "Present", "Future"] A = 1x3 string "Past" "Present" "Future".The quotes do not belong to the data. They are just added, when you display the cell string in the command window. Try this: Theme. Copy. str = 'name1,name2'; cstr = strsplit (str, ',') This is shown in the command window: Theme.B = convertCharsToStrings(A) converts A to a string array if A is a character array or a cell array of character vectors. If A has any other data type, then convertCharsToStrings returns A unaltered.It would look something like this. Theme. Copy. [ filename pathname ] = uigetfile; file = fullfile ( pathname , filename ); "file" will be a string that is the full path + file name of your selected file. Also, if a string is located in a cell, you just need to access the content of that cell. Theme.The num2cell function converts an array that has any data type—even a nonnumeric type. example. C = num2cell (A,dim) splits the contents of A into separate cells of C , where dim specifies which dimensions of A to include in each cell. dim can be a scalar or a vector of dimensions.MATLAB has logical values true and false, but in my cell array I have the strings 'True' and 'False'. What is the best way to convert these to the logical values true and false?data=str2double (cell)*2. This will leave the numbers marked by '#' with the 'NaN'. Finally, I want two things where I need some help: 1) replace the 'NaN' with the original numbers marked with '#', for instance '# 2.537' into data (1,1), and 2) convert the data matrix into a cell array of strings. The order of step 1 and 2 is not important.I want to convert a structure to a cell array where all the entries are converted to strings, including numbers. If I take the MATLAB example: s = category: 'tree' height: 37.4000 name: 'birch' I want to convert this to . c = 'tree' '37.4000' 'birch' where all entries are converted to strings, including numbers.cellfun and arrayfun can add significant overhead. There are many ways to convert a numeric array to a cell array of strings. The three highest-performance solutions are very similar in terms of performance: Looping to assign cell elements. n4 = length (Keyset); tmp4 = cell (n4,1); for i4 = 1:n4 tmp4 {i4} = sprintf ('%i',Keyset (i4)); end ...val=answer; for n=1:numel (var) % this is the code to assign value from answer to the variables created from var string array. vn=val (n); assignin ('base',char (var (n)),vn {:}) end. class (var) Here every variable has 'char' datatype which can't be used for calculations. That's why I need them to convert it into double format.X = 1×6 51 46 49 52 49 54. This list summarizes the best practices for converting text to numeric values. To convert text to numeric values, use the str2double function. It treats string arrays, character vectors, and cell arrays of character vectors consistently. You can also use the double function for string arrays.We can use the num2str () function of Matlab to convert a number into a string. For example, let's create a number and convert it into a string in Matlab. See the code below. clc number = 100 string = num2str(number) Output: number = 100 string = 100.

Marc-Olivier Labrecque-Goulet on 8 Mar 2017.When the input argument is a string array, the double function treats each element as the representation of a floating-point value. However, when the input is a character array, double instead converts each character to a number representing its Unicode® value. As an alternative, use the str2double function.str2double is suitable when the input argument might be a string array, character ...c = cellstr(S) places each row of the character array S into separate cells of c. Use the char function to convert back to a string matrix. Examples. Given the string matrix.

Convert a numeric array to a character array. A = [77 65 84 76 65 66]; C = char (A) C = 'MATLAB'. The integers from 32 to 127 correspond to printable ASCII characters. However, the integers from 0 to 65535 also correspond to Unicode® characters.you may use arrayfun in combination with an anonymous function: B = arrayfun (@ (x) {num2str (x)}, A); cellfun is a little bit faster and works also fine: B = cellfun (@num2str, num2cell (A), 'uni', 0); fastest solution is an improved version of this solution (credits to obchardon)(However, MATLAB functions that accept string arrays as inputs do accept character vectors and cell arrays of character vectors as well.) You can convert cell arrays of character vectors to string arrays. ... In fact, the string function converts any cell array, so long as all of the contents can be converted to strings.

Feb 6, 2018 · The problem is that da=data_tr (i,2); is considered as a 1x1 table by matlab (shown in the var section) and i dont know how to extract the string from it. You can try using data_tr.Var2 {i,1}. The table will automatically assign Var1, Var2, etc as variable names in a table, so your second column should be Var2. Assigning a number to a string converts the number to a string, and assigning the string to a number converts it back to a number. This does not happen with the "old-fashioned" char arrays: >> a=0; >> a(1) = sprintf('%.1e', 1/1000); Unable to perform assignment because the left and right sides have a different number of elements.datenum accepts strings, not numerical values. A possible solution is converting the second column of your data into an array of strings, and feeding it into datenum, like so: d = datenum (num2str (vertcat (IBM {:, 2})), 'yyyymmdd'); Note that this is, of course, possible only if the format of the date string is fixed in each row.You can do this by first using datetime to convert all the dates with the desired format 'dd/MM/yyyy hh:mm:ss aa', identifying dates that didn't convert using isnat, then converting those with the shortened format 'dd/MM/yyyy'.Then you can convert to a numeric value using datenum.I used the sample data from the help text of your function as input X:The quotes do not belong to the data.
