For example, access the first element of the cell array created in the previous section and convert the element to a std::string :. The variable str is a copy of the value in the cell array. Create a reference to the element and modify the value in the cell array. Copy the element, change the value, then reassign the value to the cell array.

A structure array is a data type that groups related data using data containers called fields. Each field can contain any type of data. A cell array is a data type with indexed data containers called cells , where each cell can contain any type of data. Cell arrays commonly contain either lists of character vectors of different lengths, or mixes of strings and numbers, or numeric arrays of different sizes. View more related videos.

Help Center Help Center. A cell array is a data type with indexed data containers called cells. Each cell can contain any type of data. Cell arrays are often used to hold data from a file that has inconsistent formatting, such as columns that contain both numeric and text data. Each element is within a cell. If you index into this array using standard parentheses, the result is a subset of the cell array that includes the cells. To replace the contents of multiple cells at the same time, use parentheses to refer to the cells and curly braces to define an equivalently sized cell array.

Now, store text data using a string array, and store tabular data using a table. Use cell arrays for heterogeneous data that is best referenced by its location within an array. C is a 2-by-3 cell array. When you want to add values to a cell array over time or in a loop, first create an empty array using the cell function. This approach preallocates memory for the cell array header. Each cell contains an empty array []. To read from or write to specific cells, enclose indices in curly braces.
