问题 How can I get the max (or min) value in a vector in C++ ? I have seen a few solutions for this on Google but none of them made sense to me :( Can someone explain in an easy straightforward noob way how to get the max or min value from a vector please? and am I wrong in assuming it would be more or less the same with an array? I need an iterator right? I tried it with max_element but kept getting an error? vector<int>::const_iterator it; it = max_element(cloud.begin(), cloud.end()); error:

问题 Here is the test program: void testFunc() { double maxValue = DBL_MAX; double slope = std::numeric_limits<double>::quiet_NaN(); std::cout << "slope is " << slope << std::endl; std::cout << "maxThreshold is " << maxValue << std::endl; std::cout << "the_min is " << std::min( slope, maxValue) << std::endl; std::cout << "the_min is " << std::min( DBL_MAX, std::numeric_limits<double>::quiet_NaN()) << std::endl; } int main( int argc, char* argv[] ) { testFunc(); return 0; } In Debug, I get: slope

MySQL Left Join + Min

由 徘徊边缘 提交于 2019-11-27 14:06:49
问题 Seemingly simple MySQL question, but I've never had to do this before.. I have two tables, items and prices, with a one-to-many relationship. Items Table id, name Prices Table id, item_id, price Where prices.item_id = items.id What I have so far: SELECT items.id, items.name, MIN(prices.price) FROM items LEFT JOIN prices ON items.id = prices.item_id GROUP BY items.id How do I also return the corresponding prices.id for that minimum price? Thanks! 回答1: This will return multiple records for a

Python find min max and average of a list (array)

I am having hard time to figure out how to find min from a list for example somelist = [1,12,2,53,23,6,17] how can I find min and max of this list with defining ( def ) a function I do not want to use built-in function min from __future__ import division somelist = [1,12,2,53,23,6,17] max_value = max(somelist) min_value = min(somelist) avg_value = sum(somelist)/len(somelist) If you want to manually find the minimum as a function: somelist = [1,12,2,53,23,6,17] def my_min_function(somelist): min_value = None for value in somelist: if not min_value: min_value = value elif value < min_value: min

How to refresh a jQuery UI Slider after setting min or max values?

由 我的梦境 提交于 2019-11-27 13:34:53
问题 I have a ui.slider and change it's min and max values on runtime. But these changes only get reflected in the view, when I set the values afterwards too (which causes it to fire events that are not needed). In my opinion, it should refresh the view after setting min and max too. Is there a simple workaround, seems like a refresh method is missing for the slider. $("#something").slider({ range: true, values: [25, 75], min: 0, max: 100 }); $("#something").slider("option", "min", 25); // left

Most efficient way to find smallest of 3 numbers Java?

由 天大地大妈咪最大 提交于 2019-11-27 13:27:10
问题 I have an algorithm written in Java that I would like to make more efficient. A part that I think could be made more efficient is finding the smallest of 3 numbers. Currently I'm using the Math.min method as below: double smallest = Math.min(a, Math.min(b, c)); How efficient is this? Would it be more efficient to replace with if statements like below: double smallest; if (a <= b && a <= c) { smallest = a; } else if (b <= c && b <= a) { smallest = b; } else { smallest = c; } Or if any other

How can I find the maximum or minimum of a multi-dimensional matrix in MATLAB? [duplicate]

问题 This question already has an answer here: Index of max and min value in an array 3 answers I have a 4D array of measurements in MATLAB. Each dimension represents a different parameter for the measurement. I want to find the maximum and minimum value and the index (i.e. which parameter) of each. What's the best way to do it? I figure I can take the max of the max of the max in each dimension, but that seems like a kludge. 回答1: Quick example: %# random 4 d array with different size in each dim

Java - Finding/Printing Min/Max with Array?

问题 Question: How would I go about finding min/max from array and what would the syntax look like? (( Edit: Started working on what it might look like (at the bottom of this post), but I'm not getting the syntax right )) Would like to create a method in my main class to find the students with the best and worst grades (and print) from an array of students, not sure about how the syntax would look with an array. Main.java import java.util.*; import java.io.*; public class Main { private static int

Does MINLOC work for arrays beginning at index 0? (Fortran 90/95)

由 老子叫甜甜 提交于 2019-11-27 07:22:35
问题 After using C for a while, I went back to Fortran and allocated the arrays in my code from index 0 to N: real(kind=dp), dimension(:), allocatable :: a allocate(a(0:50)) I needed to find the index of the minimum absolute value of the array, so I used MINLOC, and to check this I compared it to MINVAL: minloc(abs(a(:))) minval(abs(a)) The result of MINLOC was index 42 but the result of MINVAL corresponded to 41 . Here is the relevant section from the output: Index i a(i) 39 0.04667 40 0.02222 41
