Matlab cell array to string array

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 ...

If A has any other data type, then convertCharsToStrings returns A unaltered.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).@excaza I know, but, as I have written at the beginning of my answer, the motivation for using a separate function is that the mapping might become more complex than just strcmps.In that case it would be much easier to rewrite the one function rather than inventing a new way of how to do it with the whole arrays (which may become non-trivial).for some purpose i have cut it down it into 3 characters a string using REGEXP it gave me cells of a cell array which i was not intend to get . what now i want to do is convert every single cell into string and to perform some operations on every string

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:2. Rather than turning into a matrix you can just operate on the cell array since it seems like you have different-sized data in each element which makes it nearly impossible to combine into a character array: Use cellfun to call strsplit on each entry. out = cellfun(@strsplit, data, 'uniformoutput', false); Just use regexp to split the string ...Input array, specified as a vector, matrix, or multidimensional array. If A is a scalar, then sort(A) returns A. If A is complex, then by default, sort sorts the elements by magnitude. If more than one element has equal magnitude, then the elements are sorted by phase angle on the interval (−π, π]. If A is a cell array of character vectors ...This example shows how to create categorical arrays from various types of input data and modify their elements. The categorical data type stores values from a finite set of discrete categories. You can create a categorical array from a numeric array, logical array, string array, or cell array of character vectors.R2016b allows you to create string arrays, and R2017A allows you to use the double-quote syntax for specifying string literals. What is the practical difference between a string array (e.g ["one", "two"]) and a cell array of character vectors (e.g. {'one', 'two'}).
