Consider a classical space $ M_k(N)$ of elliptic modular forms of weight $ k$ for $ \Gamma_0(N)$ . The definition of an unramified Hecke operator $ T_{p^m}$ in terms of double cosets is the disjoint union of double cosets $ $ \Gamma_0(N) \begin{pmatrix} a&b \ c&d \end{pmatrix} \Gamma_0(N),$ $ where $ a, b, c, dRead more

I’m working on a small script to transfer views over from one database to another. I can get the view definition by using select view_definition from information_schema.views where table_name = ‘actor_info’, however the result is SELECT a.actor_id, a.first_name, a.last_name, group_concat(DISTINCT (((c.name)::text || ‘: ‘::text) || ( SELECT group_concat((f.title)::text) AS group_concat FROM ((film f JOIN film_categoryRead more

This question already has an answer here: How can I create a function with “positional” or “named” optional arguments? 6 answers I have function the needs to enable some Optional parameters and an OptionsPattern. The issue I am facing is that the options are being matched to the optional parameters when the optional parameters areRead more

1. CTR – Click-Through Rate Active clicking factor distinguishes the level of individuals who tap on connect. Typically put in a promotion, site page… and so on. The higher the CTR rate, the more individuals experienced. CTR is critical for some parts of the Digital world. 2. CPA – Cost per Acquisition Cost per AcquisitionRead more

I’d like to have a function that returns elements of a matrix: MATR = Table[i + j, {i, 0, 3}, {j, 0, 3}]; myFunc[a_,b_] := MATR[[a,b]]; I can make second definition with no arguments. In this case function returns entire matrix in MatrixForm: ff[] := MatrixForm[MATR]; I wonder if it possible to make a definitionRead more
