[MOTIVATION]

Why should we use markups in the body of our questions?

The answer is a question: which of the two versions is more likely to be understood in a glimpse and has more chances to be answered by our readers?

< Consider the following question >

I have a vector of weights W=[10,20,30,50,23434,1,2.4,2] and a matrix A=rand(100,8) and I would like to find the row-wise weighted sum of A. I am proceeding in the following way: B=zeros(size(A)); for c=1:numel(W) B(:,c)=A(:,c)*W(c); end B=sum(B,2); Somehow I get huge numbers can you please help?

< Now, consider its formatted version >

I have a vector of weights W = [10,20,30,50,23434,1,2.4,2] and a matrix A = rand(100,8) and I would like to find the row-wise weighted sum of A.

I am proceeding in the following way:

B = zeros(size(A));
for c = 1:numel(W)
    B(:,c) = A(:,c)*W(c);
end
B = sum(B,2);

Somehow I get huge numbers can you please help?

Me too.

@Elige: Yes... the first two used tinypic the latter used uploadhouse. I uploaded the first two .gif's to uploadhouse for you.

That is not relevant to this discussion. You should ask your own Question about it.

CODE

Another tip: please, please, please indent your code in MATLAB correctly first, before pasting it in.

To do this highlight your code in the MATLAB editor (for example type "Ctrl a" to select all the text in the editor), then type "Ctrl i". This "fixes/standardizes" your indentations. Then , paste your code in, and then click the "{} Code" icon. DO NOT CLICK "{} Code" before you paste in your code. That will not work.

I updated my question and content based on your instructions. However, the code is not showing in this application as I had it formatted.

Stephen Cobeldick on 12 Jun 2018

@Trude Mashburn: I just checked your question, and none of the code text has been indented.

Select the code text
Click the {} Code button
Ensure that there is a trailing empty line
Check the formatting in the preview pane, make changes as required.
Click Submit to save the new formatting.

An alternative to using the {} Code button is to simply put two space characters at the start of each code line.

BOLDFACE

1 Comment

Walter Roberson on 10 Aug 2011

Note: the bold mode only works between pairs of * in the same paragraph. If you highlight several paragraphs (with empty lines between them) and click on the Bold button, although an * will be put on the first line and last line of the selection, the bold will "break" because of the empty lines.

ITALIC

Walter Roberson on 10 Aug 2011

Note: the italic mode only works between pairs of underscores in the same paragraph. If you highlight several paragraphs (with empty lines between them) and click on the Italic button, although an underscore will be put on the first line and last line of the selection, the italics will "break" because of the empty lines.

MONOSPACED

1 Comment

Walter Roberson on 12 Aug 2011

Note: the monospaced mode only works between pairs of bars in the same paragraph. If you highlight several paragraphs (with empty lines between them) and click on the monospace button, although an bar will be put on the first line and last line of the selection, the monospace will "break" because of the empty lines.

NUMBERED LIST

3 Comments

Walter Roberson on 7 Aug 2011

Note: here must be a blank line before and after the # list

Walter Roberson on 8 Aug 2011

Note: there must be a space after the #

Walter Roberson on 12 Aug 2011

Note: the numbering sequence restarts at each empty line, so do _not_ put blank lines between the portions.

Note: the # must be after a "real" line break, where carriage return was typed at the end of the previous line; it is not sufficient to put it at what looks like the beginning of a line, if the line has been automatically wrapped down from the previous line.

HYPERLINK

1 Comment

Walter Roberson on 7 Aug 2011

Simple hyperlinks are not converted automatically by the site: that is being done by browsers.

Note: ensure that there is no whitespace space immediately after the < or immediately before the > or else the link will not be created.

Note: there must be whitespace (or beginning of line) immediately before the < or else the link will not be created. In particular, some people like to put links in brackets such as (<some link or other>) and that will not work because there must be a space before the < .

To insert an image into the body of your post, click this icon:

and either browse to a file on your computer, or specify a URL of an image on the web.

You might find it easy to use http://snag.gy. You can just type alt-PrintScreen (in Windows) to capture the active window into the clipboard. Then go to this web site and type control-v to paste it in. You can then crop if it you want. It gives you a URL that you can then paste into the URL field you see when you click the green and brown frame icon:

You can also use the paper clip icon to attach an image file to your post, but it will not be displayed. It will appear as a filename beneath your text. We would then have to right click that filename and save it to our computer, and then open the image in MATLAB or some other image file viewer. This is less convenient for readers because they can't see your picture immediately.

Click the green and brown frame icon to insert the image into the body of the message.

I did it but still it displays as a file , does it have to do anything with the image format because it's a screenshot?

Image Analyst on 11 Nov 2018

After you click Insert Image, try putting a blank line before the < < and a blank line after the > >.

madhan ravi on 11 Nov 2018

Thank you sir Image Analyst it turned out only jpg format can be viewed directly
