The editor for Matlab Answers apparently no longer allows pasting text from another source. I commonly will write notes to myself, and then use that content to submit to this forum. Why shut down this functionality???

Followup: I found that this limitation occurs when using the latest Firefox browser in Mac OS. It is not a problem with the Google Chrome browser.

I am not able to paste from MATLAB R2018a

Greg

WHYYY?

Pasting stop working with Firefox with Firefox 54 or 55. The exact release of failure appears to depend upon operating system .

On Mac it is still possible to paste using command V with Safari .

Mathworks is testing a bug fix for use with Firefox

You can paste. We do it all the time. However, you have to use keyboard shortcuts:

Copy: ctrl+c
Cut: ctrl+x
Paste: ctrl+v

On a Mac, replace ctrl with command.

What appears in the rt-click menu in a browser is context driven by the browser and not a choice made by MathWorks.

在 MATLAB Online 中打开

Images will not paste. If your image is a figure generated by code, I would suggest pasting the code, attaching any supporting files that are needed using the paperclip icon, and then run the code to create the figure here.

The one exception I've found is if I open a live script in MATLAB Online, I can copy/paste images from the text section of the live script and paste directly to Answers.

For example, consider this live script, inserted as a picture first:

If I open in MATLAB Online, copy, and then paste here, this is the result. By running the code in MATLAB Answers, then I can get the corresponding figure to appear here as well.

The displacement of a mass-spring-damper system can be described with the following initial value problem:

Let's solve this problem for the case where mass m = 1 kg, spring constant k = 9 N/m and damping coefficient c = 0 N-s/m.

m = 1; % kg
k = 9; % N/m  
c = 0; % N-s/m

Let's also apply a periodic forcing function

(Newtons)

syms y(t)
eqn = m*diff(y,t,2) + c*diff(y,t) + k*y == 6*cos(3*t);

and initial conditions

.

Dy = diff(y,t);

cond = [y(0)==0, Dy(0)==0];

% Solve

ySol(t) = simplify(dsolve(eqn,cond),500)

ySol(t) =

Plot the displacement x for

seconds.

fplot(ySol,[0 2*pi])

OK Thanks. I don't know if you have access to any internal Mathworks wishlist, but would be nice to be able to copy and paste screen shots. Particularly for questions involving GUI's and Simulink
