Then what is a function to summarize the information of a cell?

 CELL2TABLE Convert cell array to table.
    T = CELL2TABLE(C) converts the M-by-N cell array C to an M-by-N table T.
    CELL2TABLE vertically concatenates the contents of the cells in each column
    of C to create each variable in T, with one exception: if a column of C
    contains character vectors, then the corresponding variable in T is a
    cell array of character vectors.
 
    T = CELL2TABLE(C, 'PARAM1', VAL1, 'PARAM2', VAL2, ...) specifies optional
    parameter name/value pairs that determine how the data in C are converted.
 
       'VariableNames'  A string array or cell array of character vectors
                        containing variable names for T.  The names must be
                        valid MATLAB identifiers, and must be unique.
       'RowNames'       A string array or cell array of character vectors
                        containing row names for T. The names need not be
                        valid MATLAB identifiers, but must be unique.
 
    See also TABLE2CELL, ARRAY2TABLE, STRUCT2TABLE, TABLE.

Yes but looking for information for the cell so that one can use this information to manipulate the cell later

[Image Analyst]

I don't believe there is such a function, and anyway, you don't need one to manipulate the cell array later. What you do need is knowledge of what you placed into each cell. And try to avoid cell arrays if you can. Use numerical arrays, tables, or structure arrays if you can, rather than a cell array.

[alpedhuez]

I would say there should be such one that will help people to visualize what they are doing.

[alpedhuez]

"Cell arrays contain data in cells that you access by numeric indexing. Common applications of cell arrays include storing separate pieces of text and storing heterogeneous data from spreadsheets."

I have data for cities and put a data for each city in a cell. Will structural array work better in this kind of situation?

[Steven Lord]

If you feel there should be a function similar in functionality to summary but for cell arrays, I recommend you send this enhancement request to Technical Support using the Contact Support link on the Support section of the MathWorks website. Please include in your enhancement request what aspects of the summary for table and timetable arrays you would find useful in a cell version, as well as sharing information about how you would plan to use it if it existed.

Hi

Good time

I wrote this code but it gives an error

Please help me

thank you

[Walter Roberson]

You only initialize v1(1) so you have a problem when i = 3 because then you need v1(3-1) -> v1(2)
