Hi,
The data aren't distributed according to the Weibull distribution that you have traced in your graph (for s<=1). So you will never be able to adapt them to Weibull's distribution. The sample is small. How do you say it is distributed according to Weibull? With a larger sample it may turn out to be Gaussian.

Hi,
You can get the same results without calculating the Jacobian inverse matrix. See the following program:

Hi, I've made some changes to make the program give you results. I am puzzled by "vel" value.

Hi Boyer,
as you see from the following picture, the variable p is undefined. Furthermore are missing some unit of measure.

Hi! Hereafter, there are some examples that use the Newton algorithm. Lastly, there is also one related to your problem. But it is the only one that is not soluble in the presence of a singularity.

Both in maths and in engineering texts, the complex conjugated of a number or a variable or a function, is indicated with an asterisk. My attempt to create the new operator c.c. Is not satisfactory, as can be seen from the following picture:
Can you do something better?
Thank you very much!

Hi,
In the solve block you should use the comparison operator, as follows:

Hi Alan, Why, if I write the differential equation in the usual way, it gives me a different solution?
Thank you very much

Hi Alan,
Without editing the program, but simply by modifying some 3D graphic properties (eg perspective and enabling fog) the graph becomes unacceptable as you can see below:

Hi everyone, I am trying to represent on a 3D plot, spheres placed neatly one with respect to the other, as seen in the following picture.
The problem arises when the argument of the plot consists of countless elementary functions.
Is there a synthetic way to represent multiple functions so you do not have to write an endless list in the plot argument as shown below?
Thank you very much

Hi Werner, Now I tried to attach your files, but it gives me some errors. They must be stored in a compressed folder. My O. S. is w10, Java 7 version 9

thanks Werner for the precious informations.
Practically it is'nt convenient to change it. Unless, I wasn't interested in mathcad rankings. In fact, changing emails, I would be considered a new customer.

Hi, When I create an animation, mathcad saves the file with the AVI extension. It does not seem to me that there are options in this regard. And furthermore, in any case, the video so obtained, it cann't be embedded in the message page, or attach it, as mentioned elsewhere.

Hi all,
Can anyone tell me where is the small button to update the browser page?
Or, maybe, it automatically updates, unlike the previous one in which there was the update button?
Thank you

Why, can only upload video with MP3 or MP4 extension? Those with AVI extension are forbidden ....?
In short ... Every good software should have a comprehensive guide or help....
it is not possible that when you encounter a problem you have to interrogate ..... the oracle .....
