Matlab cell array to string array

I have many large cell arrays (about 10000x100 cells each) that contain character arrays, sometimes these are numbers as strings and somtimes they are '..' or 'x' or something similar. I want to convert these cell arrays to numeric matrices (double arrays), so that all "number strings" are numbers (doubles) and all the other entries zeros.

s = strcat(s1,...,sN) horizontally concatenates the text in its input arguments. Each input argument can be a character array, a cell array of character vectors, or a string array. If any input is a string array, then the result is a string array. If any input is a cell array, and none are string arrays, then the result is a cell array of ...And this is true for a scalar cell array, a vector cell array, or even a multi-dimensional cell array: it is unrelated to whether the cell array is multi-dimensional or not. Jeff Bush on 13 Jun 2018 ×MATLAB provides a rich set of functions to work with string arrays. For example, you can use the split, join, and sort functions to rearrange the string array names so that the names are in alphabetical order by last name. Split names on the space characters.

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).Cell arrays follow the same basic rules for expansion, concatenation, and deletion as other types of MATLAB® arrays. However, you can index into a cell array in two ways: with curly braces {} to access cell contents or with parentheses to refer to the cells themselves. Keep this distinction in mind when you add, delete, or combine cells in a ...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 …a(2,:) = {' '} And now you can use the {:} operation to get a comma separated list and the [] operation to concatenate these: [a{:}] ans =. I am a noob in matlab. Note that this works out because Maltab is column-major which is why when you "linearize" a matrix using the : operator, it goes down the columns first before going across the rows ...Mar 23, 2017 · I have a cell array (length of approx. 1M) called weekDays{} where each cell index is a string of one of the days of the week, Sunday...Saturday. I'm trying to create a integer array which is a mapping of the days of week to integers, for example Sunday -> 1, ..., Saturday -> 7. I created a map like this:

String arrays are supported throughout MATLAB and MathWorks® products. Functions that accept character arrays (and cell arrays of character vectors) as inputs also accept string arrays. Represent Text with Character Vectors. To store a 1-by-n sequence of characters as a character vector, using the char data type, enclose it in single quotes.Open in MATLAB Online.

I want to transform the cell array to a single column of strings = ["event A";"event B";"event A";"event C";"event C";"event A"]. It seems like cell2mat should work for this, but it gives an error: All contents of the input cell array must be of the same data type. Description. celldisp(C) recursively displays the contents of a cell array. The celldisp function also displays the name of the cell array. If there is no name to display, then celldisp displays ans instead. For example, if C is an expression that creates an array, then there is no name to display. celldisp(C,displayName) uses the specified ...

As other answers have noted, using cell arrays is probably the most straightforward approach, which will result in your variable name being a cell array where each cell element contains a string.. However, there is another option using the function STRVCAT, which will vertically concatenate strings.Instead of creating a cell array, this …str = strings returns a string with no characters. For more information on string arrays, see string. You also can use double quotes. For example, str = "" creates a string scalar that contains no characters. example. str = strings(n) returns an n -by- n string array. Each element is a string with no characters.Sometimes existing text is stored in character vectors or cell arrays of character vectors. However, the plus operator also automatically converts those types of data to strings when another operand is a string. To combine numeric values with those types of data, first convert the numeric values to strings, and then use plus to combine the text.Jun 12, 2012 · I have a certain cell of size 400x1. It basically consists of numbers in the form of string. I mean when I do. mycell{1} it gives result '1' So you can see the number 1 is in the form of string. How can I convert this into a numeric array? Syntax. C = cell(n) C = cell(sz1,...,szN) C = cell(sz) D = cell(obj) Description. example. C = cell(n) returns an n -by- n cell array of empty matrices. example.

From the Help files it seems that special cases in which str2num works while str2double does not is when the argument is whole one ... and so on. Why? Apparently this code tries to concatenate a nested cell array to a string (a cell array containing a matrix of chars which constitute the string like 'banana'). So, correct answer is. Use {:} for fruit = fruits [fruit{:} 'is a fruit'] end Magically this already produces the expected 'banana is a fruit', 'apple is a fruit', etc ... 0. A really simple way if you don't want to mess with automation: Double click on the variable in the workspace. In the Variables window click on the top-left box to select the entire cell array. Right-click -> copy. Paste to wherever you like! I have tested this with R2012b in Linux with Libre Office. It should work with Excel as well.

To enable your existing code to accept string arrays as input, add a call to convertStringsToChars at the beginning of your code. For example, if you have defined a function myFunc that accepts three input arguments, process all three inputs using convertStringsToChars . 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.A cell array is a data type with indexed data containers called cells, where each cell can contain any type of data. For example: 1×3 cell array. {[42]} {5×5 double} {["abcd"]} To access the contents of a cell, enclose indices in curly braces, such as c{1} to return 42 and c{3} to return "abcd".
