The recommended way to store text is to use string arrays.If you create variables that have the string data type, store them in string arrays, not cell arrays. For more information, see Text in String and Character Arrays and Update Your Code to Accept Strings.. While the phrase cell array of strings frequently has been used to describe such cell arrays, the phrase is no longer accurate ...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:example. C = num2cell(A) converts array A into cell array C by placing each element of A into a separate cell in C. The num2cell function converts an array that has any data type—even a nonnumeric type. example. C = num2cell(A,dim) splits the contents of A into separate cells of C , where dim specifies which dimensions of A to include in each ...A = cell2mat(C) converts a cell array into an ordinary array.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.5. I'm sure there's a way to do this but I don't know what it is.
