To run the function on a GPU, specify the input data as a gpuArray (Parallel Computing Toolbox). For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox) . Distributed Arrays Partition large arrays across the combined memory of your cluster using Parallel Computing Toolbox™.
derivative of error function - Mathematics Stack Exchange
Apr 23, 2016 · How can I calculate the derivatives $$\frac{\partial \mbox{erf}\left(\frac{\ln(t)-\mu}{\sqrt{2}\sigma}\right)}{\partial \mu}$$ and $$\frac{\partial \mbox{erf}\left ...
statistics - How to accurately calculate the error function ...
$\begingroup$ I'll agree with that assessment. I thought about mentioning the numerical instability, but the post was already long.
Approximating the error function erf by analytical functions
Aug 15, 2016 · Thus, for a standard normal distribution with $\mu =0$ and $\sigma =1$: $$\operatorname{erf}(\frac{x}{\sqrt{2}}) \approx \operatorname{Tanh}\left(\frac{x \, \pi}{2 ...
How to get the jQuery $.ajax error response text?
error: function(err) {. alert( $($(err.responseText)[1]).text() ) debugger; The question was related to the Ajax request where the dataType is "text", if you are talking about json datatype, the answers would be different. For json datatype, we have xhr.responseJSON object that …
efficient and accurate approximation of error function
$\begingroup$ My question was a bit more naive, in that I wasn't thinking about machine precision so much as how to approximate an integral with no elementary closed-form solution by elementary functions.

probability - Why is the error function defined as it is?
As it is necessary that the function should have a name, and as I do not know that any has been suggested, I propose to call it the Error-function, on account of its earliest and still most important use being in connexion with the theory of Probability, and …
real analysis - Is the error function only = 1 at infinity ...
May 10, 2018 · Probably not very useful. In the linked page, they give the asymptotic series $$\text{erf}(x)=1-\frac{e^{-x^2}}{\sqrt{\pi }}\sum_{n=0}^\infty (-1)^n \frac{(2n-1)!!}{2 ...
Is there an easily available implementation of erf() for Python?
Jul 23, 2017 · Method: we use a series approximation for erf for small x, and a continued. fraction approximation for erfc(x) for larger x; combined with the relations erf(-x) = -erf(x) and erfc(x) = 1.0 - erf(x), this gives us erf(x) and erfc(x) for all x. The …
