Answer 1

The question of how to embed a picture was answered already. Let me encourage all users to really use this feature, which is much more efficient and appealing than posting just the link to the image.

Compare http://www.n-simon.de/doc/momo_50/pics/showc4d_gait_43.gif

with this:

Here is an example with the code used: (extra spaces before and between "greater thans" so it would not execute, Do not use them like that in actual use.)

You will have to host the image somewhere. I placed my example code as a code block by putting two spaces before it so it would not actually load the image in this example.

If someone posts a question with a link like http://tinypic.com/r/14bib77/6 and I want to edit the question to embed the image I get

and that looks really ugly. Is there anything I can do besides re-uploading the image?

[Walter Roberson]

Unfortunately no.

Part of the problem is the image size: the Answers site makes no attempt to resize the images to fit the reader's screen.

[Jan]

Ask the author to create a cropped version of the image.

[Walter Roberson]

In the case of tinypic, you can right-click on the preview image and copy the URL of the preview.

[Daniel Shub]

@Jan, I might be being pessimistic, but I think that is a losing battle.

@Walter, but the preview, at least in this case, has the padding also.

[Jan]

@Daniel: You can download the image, crop it with the IPT or even in pure Matlab, save it a tinypic again and change the link in the original question. Well, of course the OP could do this also.

Finally I write this only to confirm, that this is a losing battle. Sigh.

[Walter Roberson]

I embedded that _exact_ preview, in a Question a day or so, and had no difficulty with it being off the right hand side.

[Daniel Shub]

@Walter, you tried to embed the "exact preview" but you didn't. The question is here:

http://www.mathworks.com/matlabcentral/answers/38620-processing-image-with-deconvolution

Basically there are two images: http://tinypic.com/r/2u95qwg/6 and http://tinypic.com/r/14bib77/6 You embedded the 2u95qwg image twice. If I embed that image it works for me also. The 14bib77 image does not work.

Now pictures can be uploaded directly in the forum, see: http://www.mathworks.com/matlabcentral/answers/87583#answer_97176Y . A great step to improve the usability of the forum!

[Hamad Abdin]

function [root, fx, es, iter] = modsecantmeth(func, xr, es, del, maxit)

% modsecantmeth: root location

% [root, es, iter] = modsecantmeth(func, xr, es, del maxit:

% uses Modified Secant Method to find roots of func

% input:

% func = name of function

% xr = initial guess

% es = desired relative error ( default = 0.0001%)

% del = perturbation fraction (default = 1e-6)

% output

% root = real root

% ea = approximate relative error (%)

% iter = number of iterations

% operational notes

% none.

if nargin < 2, error('at least 2 input arguments required'),end

if nargin < 3 || isempty(es), es = 0.0001;end

if nargin < 4 || isempty(del), del = 1e-6;end

if nargin < 5 || isempty(maxit), maxit = 50;end

iter = 0;

ea = 100;

while (1)

xrold = xr;

xr =xr - del *xr*func(xr)/(func(xr+(del*xr))-func(xr));

iter = iter +1;

if xr~= 0, ea = abs((xr-xrold)/xr)*100;end

data(:,iter) = [iter, xrold, xr, ea];

if ea <= es || iter >= maxit, break, end

end

root = xr; fx = func(xr);

disp('Secant Method Results')

disp('iter, old xr, new xr, |ea|')

disp('data')

can you help me to make run.
