Same -possibly- unwanted behaviours using Smath

In this period I am using Smath a lot .
Probably I have still not a clear idea of the keyboard shortcut and of other technique for copy & paste of element ...but there is something that I consider a litte bit frustrating when I work; I guess that is normal that while I am writing on the canvas I would like to copy & paste a piece of a formula somewhere else but when I do this comes up always the 3d graph as below reported ( I tried to copy the part of a formula hilighted in blu ) .

So I need to delete everything than place an equal somewhere and do again the copy & paste of a formula

There is no way in the future to improve on this ...or as usually I am missing some simple method to avoid this behaviour.

Thanks in advance and best regards

Franco

That's a wrong implementation in the plugin;

probably there is:


		public string[] SupportedClipboardFormats
		{
			get { return new string[] { DataFormats.UnicodeText }; }
		}

that should be:


		public string[] SupportedClipboardFormats
		{
			get { return new string[0]; }
		}

... [suite] Smath copy to its own clipboard. It means you can't
paste in other applications [Paint ...]. You must use a capture
tools or simply Windows "Print Screen". I'm using a freeware
Wingrab [from Norway]. It supports several types of 256 color
reduction, just excellent. If I want to downsample an image to
be pasted in Smath, transit via IrfanView, "ResizeResample",
it is a zoom up/down of best quality [Lanczos]. IrfanView has
a useful option to enhance poor image from the web. This option
is "Sharpen" ... very effective most of the time.

Try it ,,, Jean

Yes Jean exactly.

Your workaround is to place a very small text box on the canvas and then copy & paste the formula or part of it over there.

It is manageable , not as we are accustomed in all [MS] Office or other SW over this earth ...but manageable.

Hope that in a +/- distant future this issue can be addressed.

Best Regards

I see that Viacheslav has updated the plugin (3D Plot Region version 0.1.5917.*), download it and everything should go fine.

Downloaded ( better to say that I have upgraded all the plug-in ) and the problem is fixed now.

Thanks a lot to you and UNI

Hi,

I really apologize to bother again on the usability side but there are problems of copy & paste directly something from a formula in the following operators available in the functions palette:

Summation
Iterated product
Derivative
Definite Integral

If this issue could be addressed I guess that it would be a big benefits for everyone to streamline the workflow.

Best regards

Franco

Confirmed. "Past to region failed" appears.

Franco,

You are doig wrong from the premise.
'f' w/o argument is uknown to me except in some Mathematica
and similar coding. Your polynomial suite is college style.
el(a,1)+el(a,2)*x+el(a,3)*x^2+el(a,4)*x^3
That style would be very difficult to implement advanced
functions, as they are coded on index parameter. Further,
it wouldn't accommodate the Genfit model fit as we use
partial derivative wrt paramaters.

Don't worry, this mishandling will come as long as Smath
will exist. Same thing in Mathcad. Just a learning step
making advanced CAS work. BTW, you mention more problems
Summation, Iterated product ... NO example.

Joan,

I am talking of very basic things in the normal usage of a program ( every program that we are accustomed to use )and an Example of the issue is in the e-mail of Davide.

However just to be clear let's try to do a definite integral of sen(x) from 0 to 1 in Smath.
I click on the Functions palette on the Definite Integral operator.
It comes up on the canvas ..then I want simply copy & past the sin(x) function that I have used 2 milliseconds before in another part of the canvas ..and this is NOT possible .

...And the same issue happens for all the other 3 operators included in my e-mail , for all the other ones in the same palette there is no such a type of problem.
Hope that it is clear the issue even if I haven't supplied a picture

Best regards

Franco

... just try to reproduce the examples below.
The gray area needs a special construct in
"Samples Genfit Model".
What you are saying makes no sense unless your
Smath is all scrapped. If you have defined
f(x):=SQRT(sin(x), plug f(x) in the integrand
place holder, assign limits, and dx... bingo.

I am perfectly aware that my capability of explanation in English is very poor ..but make me worry that I have reached a so low level.

However I am famous for never give up ... and this is my new attempt in explaining what is happening, hoping to succeed this time3 ...with pictures

.

So as you can see a vary super basic operation is not allowed.

What I am trying to stress is the need for a CONSISTENT behaviour of the program using the same command of copy & paste with all the operators available on the palette and not with just a subset of them ...simply this.

Best Regards

Franco
