I need to compute integral of some array function, something
like:
from scipy import *
f = lambda x: array( [sin(x),cos(x)] )
integrate.quad( f, 0, 1)
Unfortunately integrate.quad requires Float type.
Any ideas how to perform this?
Thanks,
T.Kaz.

Do each function separately. The routine that scipy.integrate .quad uses
adapts to the local conditions of the function (when the function is
flat, it uses fewer samples; when steep, more).

It's not so easy to do it separately. I want to integrate function that
includes linalg.expm - as you see calculation the function is quite
expensive.

I understand, but the good integration algorithms really do need to
evaluate each dimension separately.
If you can bear algorithms that only use samples from fixed intervals,
then you can use the functions romb(), simps(), or trapz() in
scipy.integrate .
BTW, a better place to ask scipy questions would be the scipy mailing list. http://scipy.net/mailman/listinfo/scipy-user

Hi all.
I'm working here on a small project of mine. I'm not new to programming, but
I'm new to PHP. You have to understand that I'm coming from C++, OOP world,
so my code might seems a little too "object"-ified.
Anyways, I've created a wrapper class for MySQL connectivity. It's barebones
for now, no error checking or anything. So now I'm trying to create
user/session-handling class that would work with the data stored in the
database...

Dear All,
I have an Access database that tracks the progress of income tax
audits. When the taxing authorities make a change (an "Adjustment"), I
record the pertinent information in the database. At the end of the
audit cycle, these adjustments are used to compute the revised taxes
due. This computation is done in a fairly complex, but accurate and
easy to use, spreadsheet.
In the spreadsheet, there is a sheet that lists out all...

Basically, I've a JS function called ValidateForm(), which
returns true or false and controls if the form submits.
When I integrate this with .NET validators, the .NET
always adds it's own call to a function to the end of the
form onSubmit script. So if my function returns
false, .NETs function is still called and when it returns
true will basically render my code pointless.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
