How to convert cell array of string numbers into numer

The problem is even worse than you thought. Your output from REGEXP is actually a cell array of cell arrays of cell arrays of strings! Yeah, three levels! The following uses CELLFUN to get rid of the top two levels, leaving just a cell array of strings:. cellArrayOfStrings = cellfun(@(c) c{1},res);s = num2str(A) converts a numeric array into a character array that represents the numbers. The output format depends on the magnitudes of the original values. num2str is useful for labeling and titling plots with numeric values. example. s = num2str(A,precision) returns a character array that represents the numbers with the maximum number of ...I would like to export each of the outputs from the cell array to their own variable. As such I have a variable id which records the ID of each layer. This process is possible manually as follows: >> output =.

The output after converting to a character though gives me a value (!) that looks like 2 Chinese characters.If A is a string array, then B is a character vector or cell array of character vectors.. If A is a cell array or a structure, then string arrays in any cell or field of A become character vectors or cell arrays of character vectors in B.All other cells or fields of A are unaltered in B. Otherwise, the function returns A unaltered.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.The TIMM8A gene provides instructions for making a protein that is found inside mitochondria, which are structures within cells that convert the energy from food into a form that c...3. 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) B = regexp(num2str(A), '\s+', 'split');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". For more information, see Access Data in Cell ...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.Edited: MathWorks Support Team on 27 Nov 2018.
