integration

问题 I am interested in doing a 2D numerical integration. Right now I am using the scipy.integrate.dblquad but it is very slow. Please see the code below. My need is to evaluate this integral 100s of times with completely different parameters. Hence I want to make the processing as fast and efficient as possible. The code is: import numpy as np from scipy import integrate from scipy.special import erf from scipy.special import j0 import time q = np.linspace(0.03, 1.0, 1000) start = time.time() def

问题 I'm trying to validate our integration with Google Home, and as it turns out, the smart home test suite expects reporting state to be implemented. AFAIK, this is not necessary, but evidently, at least for this test suit, it is. I'm always reporting "willReportState" as false, which should be fine, and the test suite skips most devices because of this, but for some reason, it still expects thermostats to report state. Does this mean that the only way to get our integration approved and listed

问题 I hit database get 10 employees; on base of each employee i hit another database and fetch some information and concatenate the same. As per my understanding, It can be done either in .process() or in .enrich() (using aggregator) .to("jdbc:masterdata?outputClass=com.diavry.integrator.Employee") .to("log:?level=INFO&showBody=true") .process(e -> { List<Employee> eiEmployees = (List<Employee>) e.getIn().getBody(List.class); for (Employee employee : eiEmployees) { PreparedStatement statement =

问题 I'm setting up a simple PHP form to send transactions to sagepay using form integration, the cryptkey is setup as follows: $PAYMENT_CRYPT = "VendorTxCode=website &Amount=$total &Currency=GBP &Description=Ticket &SuccessURL=EDITED-OUT/registered-thanks &FailureURL=EDITED-OUT/registered-fail &BillingSurname=$surname &BillingFirstnames=$firstname &BillingAddress1=$address1 &BillingCity=$city &BillingPostCode=$postcode &BillingCountry=UK &DeliverySurname=$surname &DeliveryFirstnames=$firstname

问题 Updated Question Following from my original post, with the use of @Attack68 's code, I have created a program that successfully evolved the function with a choice of multiplicative functions based on a random variable. However, now I am receiving an error saying the list indices must be integers (even though I'm fairly sure they are), I'm not sure what has happened, The code is as follows: import numpy as np import scipy.integrate as integrate x=np.linspace(0.0,1.0,100) n=10 #iterations d=700

问题 I need help finding an integral of a function using trapezoidal sums. The program should take successive trapezoidal sums with n = 1, 2, 3, ... subintervals until there are two neighouring values of n that differ by less than a given tolerance. I want at least one FOR loop within a WHILE loop and I don't want to use the trapz function. The program takes four inputs: f : A function handle for a function of x . a : A real number. b : A real number larger than a . tolerance : A real number that
