Aug 17, 2011 · From what I read in the official Matlab docs, this container resembles a cell-array and most of the array-related functions should work out of the box. For your case, new solution would be: a=repmat('Some text', 10, 1); This solution resembles a Rich C's solution applied to string array. I have a cell array, where each cell is a string of the following form: A{1} = hello, world, the, hello, the, how, are, you, world I would like to retain only the unique words, to give me a new char array that will go into an output cell array: B{1} = hello, world, the, how, are, you unique() does not seem to cut it.Apr 28, 2014 · I have created a function which takes vectors for input variables and returns a cell array for each set of inputs.

To create a cell array with a specified size, use the cell function, described below. You can use cell to preallocate a cell array to which you assign data later. cell also converts certain types of Java ®, .NET, and Python ® data structures to cell arrays of equivalent MATLAB ® objects.Link. The expressions converting a "row cell of cells" to the corresponding "row vector" are. B = [ A { : } ] C = [ B { : } ] The expression for converting a 2-D cell of cells to the corresponding 2-D matrix is. C = repmat (cell2mat ( [ A {:} ] ),size (A)) Sign in to answer this question.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.

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" ;Jun 3, 2012 · 5. I'm sure there's a way to do this but I don't know what it is. Suppose I have a vector. v = [1.02 2.03 3.04]; and I want to convert this to a cell array using a format string for each element: ' %.3f'. (3 spaces before the %.3f) Introduction to Cell to String MATLAB. There are two commands used to covet cell data into string format one is char and the other is a string. char and string commands extract all the data from cell arrays and stored in the form of string. In Matlab, we use string notations as data in single or double quotes ( “ ” or ‘ ‘ ).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).5. Link. Open in MATLAB Online. Theme. Copy. [tf, idx] = ismember (Airport_actual, Airport_data); tf will be true if it is found, and idx will be the index it was found at.

Open in MATLAB Online. To convert a cell array of character vectors to numbers, you can use the str2double function. This function is the simplest method. Theme. Copy. C = {'0.000000'; '10.000000'; '100000.000000'}; M = str2double (C) The cell2mat function converts a cell array of character vectors to a character array, and only if all the ...Each of the above is its own cell within the array - i think this is called a cell array (i have not dealt with strings in matlab before) What i want is the same matrix, except I want to remove the '' in each cell, and I want to actually DO the divisions. i.e '2/8' becomes 0.25 etc

Take a look at the documentation. MATLAB makes it very easy to convert to and from Java types. Handling data returned from Java; Dealing with Java arrays; You can convert an array of Java strings to either a cell or char array in MATLAB. Using cell arrays can work even with jagged arrays (which are permitted in Java). Here are two …And it was awful. Given past reputation of inefficiency, I still don't trust looping in Matlab. Post-R2016b, one can convert a string array to cell array with num2cell and then to table with cell2table. Table can be written to csv file with writetable. This is actually fast, as writetable is fast. Only num2cell slows down the whole process a ...The corresponding character vector would be fp31 {1} Sign in to comment. If your cell array is this: access the elements using brackets: which will be a string array. Sign in to comment. Try this: c = char (fp31) % Create 2D character array.9. You have a cell array of char, not strings. string and char mean different things since the release of R2016b. You can prepend a char array to a cell array in the same way how cell arrays are combined. In the similar way, you can also combine a cell array of char with a string array or a simple char array with a string array which will ...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.Then you do not have to make any other changes to code you had written to work with string arrays. ... then B is a string scalar. If A is a cell array of character vectors, ... Thread-Based Environment Run code in the background using MATLAB® backgroundPool or accelerate code with Parallel Computing Toolbox™ ThreadPool.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. 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'.
