minimum

Having 2-dimensional array, A , I want to find minimum number in the array. However I can have more than one of that number. How can I find the [row col] of all minimum value? Example: 2 3 4 2 1 6 7 1 9 8 3 1 It should return [2,1] [2,4] [3,4] find will do the trick: [I,J] = find(A == min(A(:)) ); disp([I J]) 2 1 2 4 3 4 I belive this should work [row,col]=find(a==min(a(:))) where a is your matrix. Find can also output a linear index if you give just one output. 来源： https://stackoverflow.com/questions/14205780/find-all-minimum-elements-of-2-dimensional-array-in-matlab

As stated above: I wish to compute the minimum (and/or maximum) of a continuous variable over time. Here is a minimal example to demonstrate: model MinMaxTest Real u; Real u_min(start = 10); Real u_max(start = -10); equation u = sin(time / 180 * Modelica.Constants.pi); u_min = min(u, u_min); u_max = max(u, u_max); annotation(experiment(StartTime = 0, StopTime = 360, Tolerance = 1e-06, Interval = 1)); end MinMaxTest; u is the arbitrary continuous variable (for demo purposes a simple sinus wave). u_min / u_max is the minimum/maximum over time. Obviously the expected result is u_min=-1 and u_max

In this code construct: public MyClass(Integer... numbers) { do_something_with(numbers[]); } is it possible to require that numbers contains at least one entry in such a way, that this is checked at compile-time? (At run-time, of course, I can just check numbers.length.) Clearly I could do this: public MyClass(Integer number, Integer... more_numbers) { do_something_with(number, more_numbers[]); } but this isn't going to be very elegant. The reason I would like to do this is to make sure that a sub-class does not simply forget to call this constructor at all, which will default to a call to

I will preface this by saying it is homework. I am just looking for some pointers. I have been racking my brain with this one, and for the life of me i am just not getting it. We are asked to find the minimum element in a list. I know i need a sublist in here, but after that i am not sure. any pointers would be great. thanks. /** Find the minimum element in a list. * * @param t a list of integers * * @return the minimum element in the list */ public static int min(List<Integer> t) { if (t.size() == 1){ return t.get(0); } else{ List<Integer> u = t.subList(1, t.size()); In the most general sense

how would one go about finding the minimum value in an array of 100 floats in python? I have tried minindex=darr.argmin() and print darr[minindex] with import numpy (darr is the name of the array) but i get: minindex=darr.argmin() AttributeError: 'list' object has no attribute 'argmin' what might be the problem? is there a better alternative? thanks in advance Python has a min() built-in function : >>> darr = [1, 3.14159, 1e100, -2.71828] >>> min(darr) -2.71828 If you want to use numpy, you must define darr to be a numpy array, not a list : import numpy as np darr = np.array([1, 3.14159, 1e100

I want to define a minimum version to CMake with "cmake_minimum_required" facility. I have seen that some project set minimum version 2.8 some others set 3.0 or 3.2. I would like to learn your opinions and best practices about the topic. The cmake_minimum_required() function is used to avoid any cryptic error messages due to the CMakeLists.txt assuming a later version of CMake than the one installed on the current host. As an example, failing early, and with a clear message... CMake 3.2 or higher is required. You are running version 2.8.12.2 ...is to be preferred over something more cryptic
