Subdivide a cell, based on the number of columns, inside a for loop

Hi! I would like to compact the rows 'char2string1', 'char2string2', ... inside a for loop. How could I do this?

char2string = importdata("char2string.mat");

num_char2string = width(char2string);
Col = 6;
Row = num_char2string/Col;
Row = round(Row,0);

% I would like to compact these rows because they have to depend by 'Col' and 'Row'
char2string_1 = char2string(1,1:Col);
char2string_2 = char2string(1,Col+1:Col*2);
char2string_3 = char2string(1,Col*2+1:Col*3);
char2string_4 = char2string(1,Col*3+1:Col*4);
char2string_5 = char2string(1,Col*4+1:end);

This is what the data actually looks like:

S = load('char2string.mat');
C = S.char2string % storing scalar strings in a cell array is very inefficient. Use a string array instead.

C = 1×28 cell array
  Columns 1 through 16

    {["54"]}    {["55"]}    {["56"]}    {["57"]}    {["58"]}    {["59"]}    {["60"]}    {["61"]}    {["62"]}    {["63"]}    {["64"]}    {["65"]}    {["66"]}    {["67"]}    {["68"]}    {["69"]}

  Columns 17 through 28

    {["70"]}    {["71"]}    {["72"]}    {["73"]}    {["74"]}    {["75"]}    {["76"]}    {["77"]}    {["78"]}    {["79"]}    {["87"]}    {["88"]}

Please show us the exact output that you require from this input data.

Note that storing scalar strings in a cell array is very inefficient and means that you do not get any of the benefits of using a string array. You should use a string array, just as the MATLAB documentation recommends:

Hi @Stephen23, I want to get the variables 'char2string_1', 'char2string_2',...,'char2string_#' (as reported in my question) as the end result.

However, in this case the values of 'char2string_#' depend on Col=6. I would like to generalize what I wrote, with a for loop for example, so that I can get a similar result with a different value of Col.

For example, for Col=4 I should get this:

char2string = importdata("char2string.mat");

num_char2string = width(char2string);
Col = 4;
Row = num_char2string/Col;
Row = round(Row,0);

char2string_1 = char2string(1,1:Col);
char2string_2 = char2string(1,Col+1:Col*2);
char2string_3 = char2string(1,Col*2+1:Col*3);
char2string_4 = char2string(1,Col*3+1:Col*4);
char2string_5 = char2string(1,Col*4+1:Col*5);
char2string_6 = char2string(1,Col*5+1:Col*6);
char2string_7 = char2string(1,Col*6+1:Col*7);

In the case of Col=4, the values of 'char2string_#' are 7, while in Col=6 the values of 'char2string_#' are 5.

I would like to compact the rows with 'char2string_#' and get them directly from a for loop for example.

How did you obtain the data? Did you get it as output from some code? As @Stephen23 mentions above, storing in that manner is not efficient.

And why do you want to generate Dynamically named variables?

I don't know what you exactly want but this could be your answer:

for i = 7:-1:1

char2string_(i) = char2string(1,Col*(i-1)+1:Col*i);

end

I don't know what you want to do, what is supposed to come out and also how useful all this is.
