Text in while loop creating matrix
显示 更早的评论
I was trying to create a matrix with text in some cases, but I can't. I tried with advices from other answers, but it didn't work.
The text which I want to include is «start» and «end» for two different cases like this:
NM = 5
FF = zeros(NM*2,2);
start = 'start';
ending = 'end';
i=1
while i<=NM
FF(i*2,1) = i
FF(i*2-1,1) = i
FF(i*2,2) = fprintf(start);
FF(i*2-1,2) = fprintf(ending)
i = i+1
end

Numeric arrays cannot contain characters.
You could obtain the character code values and store those in a numeric array.
As its documentation makes quite clear, the output of fprintf is the number of bytes printed. It is doubtful that your fprintf usage helps with your stated goal.
Please show an example of what you expect the output to look like.

You have to use cell arrays if you want to mix text and numbers. And fprintf returns the number of printed bytes, so you directly assign the string to the cell, w/o fprintf:
NM = 5
FF = cell(NM*2,2);
start = 'start';
ending = 'end';
i=1;
while i<=NM
FF{i*2,1} = i;
FF{i*2-1,1} = i;
FF{i*2,2} = start;
FF{i*2-1,2} = ending;
i = i+1;
end
