max

问题 I need to calculate the max and min of the wave height according to the direction from which it comes, that is to say, I have two variables: Hs (wave height) Direction (direction of the swell) And I need to know the maximum wave height for waves with a direction between 11.25 and 33.75 degrees. For now, use the function: Max (Hs [Direction [11.25: 33.75])) But I do not agree the result with the data that I have. 回答1: Assume your dataframe is called df , your variables are called Hs and

问题 How do I extend theanos downsample.max_pool_2d_same_size in order to pool not only within a feature map, but also between those - in a efficient manner? Lets say i got 3 feature maps, each of size 10x10, that would be a 4D Tensor (1,3,10,10). First lets max pool ((2,2), no overlapping) each of the (10,10) feature map. The results are 3 sparse feature maps, still (10,10) but most values equal to zero: within a (2,2) window is at most one value greater than zero. This is what downsample.max

问题 Is there a limit on a value string in php Associative array? I have a query that returns value of GROUP_CONCAT as CSV for an array element. When I run the query directly, I see all values being returned. When I print the array in PHP, the string is truncated. Not sure how get around it? Any ideas? More info: I just var_dump the results I got from query. Here it is. It shows 1024. Looks like there is a limit. What is it? array(5) { ["FIELD_ID"]=> string(3) "232" ["answers"]=> string(1024) "48

问题 I'm trying to write a max function that operates on Seq Int . It should return the index with maximal value . Here is what I have: (declare-fun max ((Seq Int)) Int) (assert (forall ((A (Seq Int))) (=> (> (seq.len A) 0) (and (<= 0 (max A)) (< (max A) (seq.len A)) (forall ((i Int)) (=> (and (<= 0 i) (< i (seq.len A))) (<= (seq.nth A i) (seq.nth A (max A)))))))) ) (assert (= (max (seq.++ (seq.unit 8) (seq.unit 3))) 0)) ;(assert (= (max (seq.++ (seq.unit 8) (seq.unit 3))) 1)) (check-sat) When I

问题 I want to solve a stock problem. I have stock from some articles in a specific store and I want to find out which store in the same country has the highest stock of this specific item. I use the table below for information input Colom A: Article number Colom B: Country Colom C: Stock Colom D: Store number For instance: I would like to know for article 884 in Netherlands, which store has the highest stock. The outcome would be store 1. I'm not able to use the formulas MAXIFS :(. Is there a

问题 I have a query that I need to edit. Currently, it returns 2 columns of data, a case label and the count (or total number of cases) handled during the previous 7 day period starting yesterday. I need to change this output so that only 6 labels are in the output (i.e - always 6 rows of data). These rows need to be the top 5 labels and the sum of the remaining labels as the 6th label (called "Other"). This is because this output is fed to a PHP script that presents the data on a web-based

问题 Below I attempt to assign to value the maximum Long value, then add to it the minimum positive Double value possible. I then try to detect that the value is greater than the maximum Long value. Double value = new Long(Long.MAX_VALUE).doubleValue(); value += Double.MIN_VALUE; if (value < -(new Long(Long.MAX_VALUE).doubleValue()) || value > new Long(Long.MAX_VALUE).doubleValue()) { // Expecting code here to execute, but it doesn't. } Studying the values involved shows that value has the final

问题 I want to know if there is something in the standard, like a #define or something in numeric_limits which would tell me the maximum number of base-10 digits in the integral part of a floating point type. For example, if I have some floating point type the largest value of which is: 1234.567. I'd like something defined in the standard that would tell me 4 for that type. Is there an option to me doing this? template <typename T> constexpr auto integral_digits10 = static_cast<int>(log10(numeric

问题 I am using select field1, max(updated_date) from mytable . I get the correct value for max(updated_date) , i.e. the largest date. However for field1 I just get the the value for the first record, i.e. "ta1" when I really want the "ta3" value from the third record (the one with the max date value). e.g. +------------+---------------------+ | field1 | update_date | +------------+---------------------+ | ta1 | 2012-03-11 11:05:15 | | ta2 | 2012-03-11 11:05:32 | | ta3 | 2012-03-11 11:05:56 | +---
