Matlab cell array to string array.
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. Splitting changes names from a 5-by-1 string array to a 5-by-2 array.
To convert nonscalar string arrays or cell arrays to numeric arrays, use the str2double function." given that the Help itself suggests using str2double (!), I don't see the point in keeping the str2num function. From the Help files it seems that special cases in which str2num works while str2double does not is when the argument is whole one ...Winding nylon string around a spool by hand is too time-consuming.

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.
Actually, it should be pointed out that this method doesn't work if you are comparing two arrays of different size (i.e. if instead of 'KU' on the left side, you have an array of strings). Vidar's solution does work in that case (quite nicely), so is more general. –
Each 11 digit row represents a float number, where the last 10 digits are the numbers after the dot. How can I convert that cell array to an array (1000x1) of decimal floats for example :
11. You can use {} instead of [] to build a cell, or you can use strsplit to build an arbitrary length cell of strings representing numbers from 1 to N: data = strsplit(num2str(1:N)); Update: The fastest way to do this now is with the undocumented sprintfc function (note the "c" at the end) which prints each element to it's own cell:Converting an cell array into string in MATLAB. 1. MATLAB convert string representing array to actual array? 0. how to convert a number array to a single string in ... Create a string with the same characters, using double quotes. Though it stores 11 characters, str is a 1-by-1 string array, or string scalar. If you call length on a string scalar, then the output argument is 1, no matter how many characters it stores. str = "Hello World" ; L = length(str) L = 1. I am trying to grab data from an excel spread sheet and grab only the information from cells that match a string. Eg. if cell A10 contains the word 'Canada' it should return that cell. I have triedThe two main ways to process numeric data in a cell array are: Combine the contents of those cells into a single numeric array, and then process that array. Process the individual cells separately. To combine numeric cells, use the cell2mat function. The arrays in each cell must have compatible sizes for concatenation.The trick I'm exploiting is that sprintf can take a cell array, and then outputs a concatenation of multiple strings. However, this behaviour appears to be undocumented, and as of Matlab 2012b, Matlabs Code Analyzer has …
5. I'm having the cell array res with cells 3x2, each of them containing a string. I want to apply regexp to each cell and it should look like that: fin = cellfun(@regexp(res, '\.', 'split'),res,'UniformOutput',false) however it doesn't do the job. Anyone knows how it can be combined properly?I need more context here for what you are trying to accomplish, but assuming you want to still be able to access each individual number as a string, a cell array is probably the best approach you can take: A = [1 2 3] num2cell(num2str(A)) (Of course, you'd still have to remove the stray spaces from the ans) answered Aug 28, 2012 at 17:59.The two main ways to process numeric data in a cell array are: Combine the contents of those cells into a single numeric array, and then process that array. Process the individual cells separately. To combine numeric cells, use the cell2mat function. The arrays in each cell must have compatible sizes for concatenation.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 ...Data Type Conversion. Convert between numeric arrays, strings and character arrays, dates and times, cell arrays, structures, or tables. MATLAB ® has many functions to convert values from one data type to another for use in different contexts. For example, you can convert numbers to text and then append them to plot labels or file names.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 process of synthesiz... You can create a string scalar by enclosing a piece of text in double quotes. str = "Hello, world". str =. "Hello, world". To create a string array, you can concatenate string scalars using square brackets, just as you can concatenate numbers into a numeric array. str = [ "Mercury" "Gemini" "Apollo" ; Avoid using cell arrays of strings. When you use cell arrays, you give up the performance advantages that come from using string arrays. And in fact, most functions do not accept cell arrays of strings as input arguments, options, or values of name-value pairs.Neanderthals, new evidence shows, made fiber cordage — a skill we have never before attributed to them.

It's a cellstr array, and yes, it can be confusing how to address them. The content of the cell is a character string referenced by "the curlies" where as the cell or a set of cells are addressed with regular parens. There's just no difference in what V or V(1) are; the latter is just a single cell of the former array.

Vidar's solution does work in that case (quite nicely), so is more general. –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".

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.This MATLAB function returns a string with no characters. If the size of any dimension is 0, then str is an empty array.. If the size of any dimension is negative, then strings treats it as 0.. Beyond the second dimension, strings ignores trailing dimensions with a size of 1.For example, strings(3,1,1,1) produces a 3-by-1 vector of strings with no characters.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 ...
