I found how to enter a number matrix posted on the web page https://esc113.blogspot.com/2022/11/data.html.
See my code:
url = 'https://esc113.blogspot.com/2022/11/data.html';
a= webread(url);
b= extractHTMLText(a);
fID=fopen("abc.txt",'wt');
fprintf(fID,"%s",b);
fclose(fID);
fID=fopen("abc.txt",'rt');
tline = fgets(fID);
tline = fgets(fID);
tline = fgets(fID);
tline = fgets(fID);
for i=1:20
tline = fgets(fID);
A(i,:)=sscanf(tline,'%g');
end
A
But I think my solution is to mach complicated and not universal.
Can somebody show me shorter solution?
Thank you.

Hi Vasiliy,
MATLAB offers inbuilt functions for text parsing and extractions. You can find elements from the html tree of your webpage.
url = 'https://esc113.blogspot.com/2022/11/data.html';
a= webread(url);
% Generate HTML tree
tree = htmlTree(a)
% Find required element using css selectors
element = findElement(tree, '.post-body');
% Extract text from the element
str = extractHTMLText(element);
You can also refer to the following documentation.
