Answered 2022-Mar-08 at 02:03Often when translating MATLAB it's important to get shapes/sizes correct. But when I run your code in Octave I see all variables are (1,1), "scalar". So dimensions shouldn't be an issue.

QUESTION
I am trying to predict melting temperature (Tm) values for the following sample data using the R DRC library function as shown below to mimic the calculation in GraphPad PRISM using Boltzmann sigmoid function. I selected G.4() function in the DRC package which was the closest self-starting model that was providing Tm values very close to the Boltzmann sigmoid function in PRISM. I am sure it is not the most appropriate choice. I need advice on the correct R library function.
The Boltzmann sigmoid equation used by GraphPad PRISM software:
Y=Y2+((Y1−Y2)/(1+exp((V50−X)/slope))
Four-parameter Gompertz model used in G.4() function in R DRC library:
f(x)=Y2+(Y1−Y2)exp(−exp(b(log(X)−e))).
...ANSWER
Answered 2021-Nov-02 at 22:03The "Boltzmann sigmoid function" is exactly what Pinheiro and Bates call the "four parameter logistic function", since it's really just a rescaled version of the logistic function with different minima and maxima. As such a self-starting version is already built into R in the form of the SSfpl
function. So it's as simple as
QUESTION
I want to play around with waLBerla (website and gitlab), which is a C++ library that can be used to simulate certain physical behavior, like fluid dynamics using the Lattice Boltzmann method, but having major difficulties on how to properly set up my CMakeLists.txt, as I don't have much experience with that.
I followed the instructions to install the library, using some of the dependencies like OpenMP, CUDA and OpenMESH, which went fine.
But when trying to compile for example one of the tutorials, I just can't get it to work. So far I have the following Cmake file, where I manually list all the static libraries that have been build when compiling waLBerla:

And here is my code:
...ANSWER
Answered 2020-Dec-05 at 16:38There are a few things here. I don't think x and y were ever flipped, or at least when I assumed they weren't, everything seemed to work fine. I also cleaned up a few parts of the code, for example, I'm not sure why you call two different histograms; and I think there may have been problems handling the single element tuple of parameters. Also, for curve fitting, the initial parameter guess often needs to be in the ballpark, so I changed that too.
Here's a version that works for me:
QUESTION
I have come across a very strange problem where i do a lot of math and the result is inf
or nan
when my input is of type , but i get the correct (checked analytically) results when my input is of type
. The only library functions i use are
np.math.factorial()
, np.sum()
and np.array()
. I also use a generator object to sum over series and the Boltzmann constant from scipy.constants
.
My question is essentially this: Are their any known cases where np.int64
objects will behave very differently from int
objects?
When i run with np.int64
input, i get the RuntimeWarnings: overflow encountered in long_scalars
, divide by zero encountered in double_scalars
and invalid value encountered in double_scalars
. However, the largest number i plug into the factorial function is 36, and i don't get these warnings when i use int
input.
Below is a code that reproduces the behaviour. I was unable to find out more exactly where it comes from.

int64
is a 64-bit integer, meaning it consists of 64 places that are either 0 or 1. Thus the smallest representable value is-2**63
and the biggest one is2**63 - 1
- Python's
int
is essentially unlimited in length, so it can represent any value. It is equivalent to aBigInteger
in Java. It's stored as a list ofint64
s essentially that are considered a single large number.
What you have here is a classic integer overflow. You mentioned that you "only" plug 36 into the factorial function, but the factorial function grows very fast, and 36! = 3.7e41 > 9.2e18 = 2**63 - 1, so you get a number bigger than you can represent in an int64!
Since int64
s are also called long
s this is exactly what the warning overflow encountered in long_scalars
is trying to tell you!

Answered 2020-Nov-04 at 16:35the reason why your sys.path.append
statements have no effect is that you start the paths with a trailing "/", which indicates that they are absolute paths, even though they should not be.
You could either add the full paths to the modules you would like to import or, if you want to use relative paths, do something like this:

QUESTION
In the article that I am interested in, it states that the data is well represented with a Maxwellian distribution and it also provides a Mean speed (307 km/s) and 1 sigma uncertainty (47 km/s) for the distribution.
Using the provided values, I have attempted to re-generate the data and then fit it with the Maxwellian distribution using the python scipy.stats.
As it described in here, maxwell function in scipy takes two input, 1) "loc" which shifts the x variable and 2) "a" parameter which corresponds to the parameter "a" in the maxwell-Boltzmann equation.
In my case, I have neither of these parameters, so using the Mean and variance (sigma^2) description in wiki page, I have attempted to calculate the "a" and "loc" parameter. Both mean and sigma parameters are only dependent on "a" parameter.
The first problem I have encountered was the "a" parameter that I get from Mean (a = 192.4) and sigma (a = 69.8) are different from each other. The second problem is that I don't know how can I obtain the exact loc (shift) value from Mean and sigma.
Based on the shape of the distribution (where mean speed values fall in the graph, check figure 2), I tried to guess the "loc" value and together with the "a" value obtained from sigma (a = 69.8), I have generated and fitted the data. Approximately it seems correct, but I don't know the answer to the questions I mentioned above and I need some expert's guidance on this. I appreciate any help.
...ANSWER
Answered 2020-Aug-08 at 01:57Well, mean value is affected by location, and sigma won't.
So compute a
from sigma, compute mean as if loc=0, find the difference and assign it to location, sample 100K RVs to check if
sampled mean/stddev are close enough.

Install boltzmann
You can use boltzmann like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
