I have to homework my instructor say that, you must enter a string like ' what is the wheather will 17 may 2020 ? ' the program convert to this;

for colon numb of cell=4

-------------------

Wha

Tist (' ' spaces can not count)

Hewh

Eath

....

__ma (every nonstring replace with '_' )

Y___

- first character of every group upper the other ones lower.

ı am second step of progress. ı couldnt reshape cell array that is constitute with charecters at least could anyone help me this subject (you can help me nonstring and space replacement step if you understand) ?

text1=input('please enter the text','s');
text=num2cell(text1);
lengtht=length(text);
linelength=input('enter line length'); %colons
groupnumb=(lengtht/linelength); % group number (row)
    

reshaped=reshape(groupnumb,linelength,text); % the constitue that ı write above

I am sorry but publishing official document of faculties is not legal.

I think I somewhat understand the question. Get some ideas from this code

str = 'what is the wheather will 17 may 2020 ?';
str = lower(str);
str = strrep(str, ' ', '');
str = regexprep(str, '[^a-z]', '_');
str = [str repmat('_', 1, ceil(numel(str)/4)*4-numel(str))];

str_ = reshape(str, 4, [])';
str_(:,1) = upper(str_(:,1))

Since this is a homework question, so I recommend you to understand the working of each function by reading documentation.

ı am thankful your answer and I have done my homework truly but reshape function doesnt work when ı write your 7th line. enter real number or integer

[Ameer Hamza]

Can you paste you code here which gives the error? Are you using some other input string?

[Ugur Sahin]

ı have done dimensions couldn't pair ı have seen now thanks lot.
