Character vectors are not strings, so isstring returns 0. …Selected part of the text, returned as a string array, a character vector, or a cell array of character vectors. token includes all text starting at the first character that is not a delimiter and ending at, but not including, the next delimiter. str and token are the same data type. Data Types: string | char | cell.You can represent text in MATLAB ® using string arrays. Each element of a string array stores a sequence of characters. The sequences can have different lengths without padding, such as "yes" and "no". A string array that has only one element is also called a string scalar. By default, the join function combines strings along the last dimension with a size that does not equal 1. To combine the strings along the first dimension, specify it as an additional input argument. newStr = join (str,1) newStr = 1x2 string "Carlos Ella Diana" "Sada Olsen Lee". I am using Matlab 2018a Appdesigner to build an App. When I initialize the App, I read-in text from an Excel file using xlsread and save it as a public variable/property.

If str is a string array, then so is newStr.Otherwise, newStr is a cell array of character vectors.newStr does not include the whitespace characters from str.S = readlines (filename) creates an N-by-1 string array by reading an N-line file. example. S = readlines (filename,Name,Value) creates a string array from a file with additional options specified by one or more name-value pair arguments. For example, 'EmptyLineRule','skip' skips empty lines.C = cat (dim,A,B) concatenates B to the end of A along dimension dim when A and B have compatible sizes (the lengths of the dimensions match except for the operating dimension dim ). example. C = cat (dim,A1,A2,…,An) concatenates A1, A2, … , An along dimension dim. You can use the square bracket operator [] to concatenate or append arrays. Math makes little sense on cell arrays because cell arrays are used in 99% of cases for strings or function handles. Search is same as vectorized. Sorting works where it makes sense, i.e. where objects can be compared like strings. For many years I thought of cell and double arrays as something different.

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); However, you can also change your call to REGEXP to get rid of one level, and then use ...edit: I am trying to avoid using xlabel, ylabel, zlabel. Having separate functions for each axis forces me to use the switch statement. I would like to replace that with a single statement where I refer to the label for each axis by a number index instead of with separate functions.Matlab returns those 2 logical vectors: Check_31 = 1 1 1 Check_41 = 1 1 0. So as you see, the character "_" is not the last element of the string present in the cell {4,1}. Now if we use strcmp (on the whole cell array; we don't need to index specific cells to check whether some string is present): Check_ABC = strcmp (myArray,'ABC') We also get ...String arrays are supported throughout MATLAB and MathWorks® products.
