Hi,

I'm trying to figure out how to get the HermitianTranpose vector to distribute over a sum of vectors. Maple seems to want to ignore the linearity of the conjugate operation.

See the example code attached.

Thanks.

By default, CodeGeneration generates temporary names during optimize of t####. For compatibility with other code, I would like to have flexibility in choosing the preamble to the temporary variable name ("t" is default). Is there a way to do this?

I don't see anything in the documentation, but it seems like something one should be able to do.

(My target language is Python - although I'm not really using Python, the syntax is compatible).

I am trying to get Maple to recognize that

diff(x^n,x) does not equal n*x^(n-1), but rather 0 if n=0, or n*x^(n-1) otherwise.

This comes up when differentiating an infinite sum (power series). The constant term gets transformed into n/x instead of becoming zero. Maybe this is really a bug/lack of feature in how sum/Sum works.

For example: diff(Sum(x^n, n = 0 .. infinity), x) yields

Does anybody have a fix to get the differentiation right (other than expanding some terms of the series before taking the derivative)? 

(edited) Please note I am not trying to get an answer to this specific question. It is just illustrates a simplified example of behavior that leads to other bizarre results. Please see the attached worksheet for more weirdness: Problems_with_summation_Mapleprimes.mw

Hi,

I just upgraded to Maple 2021 and started getting strange results - similar calculations seemed to work in Maple 2020.

I am looking at correlated bivariate normal distributions. When doing a fully symbolic verification of the normalization, I get an incorrect result of infinity. I also get strange results when integrating over a circular region, but the normalization seemed to be a very elementary calculation.

Maybe someone can check this make sure I'm not losing my marbles. I've attached a worksheet.

Thanks.

Hi,

I am looking to have Maple compute the following:

The return value is:

Is there any way to get this to simplify appropriately? The problem is with the case k=1, which should just be 0.

What is the best way to expand this if I want to see some of the first few terms?
