번역 댓글:dpb2015년 12월 11일 채택된 답변:dpb MATLAB Online에서 열기 Hello, I am trying to figure out on how to extract data only when the number in one of the row increases; for example: a = [1;1;1; 2;3;4;5;6;7;8;...
下面是 MATLAB unique 函数的源码实现: function [C,IA,IC] = unique(A) % 将 A 排序 [ASorted,ind]=sort(A(:)); % 寻找重复元素 d=[true;diff(ASorted)>0]; C=ASorted(d); % 记录 C 中元素的位置 IC=accumarray(cumsum(d),ind,[],@min); % 生成 IA 向量 if nargout>1 MATLAB的unique...
(1) 首先对输入的矩阵或向量A进行排序,这里采用了MATLAB内置的sort函数进行排序。 (2) 然后依次比较相邻的元素,找出重复的元素。 (3) 最后将重复的元素去重,只保留其中的一个。 下面是MATLAB unique函数的源码实现: function [C,IA,IC] = unique(A) % 将A排序 [ASorted,ind]=sort(A(:)); % 寻找重复...
The unique function supports GPU array input with these usage notes and limitations: The 'legacy' flag is not supported. 64-bit integers are not supported. For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox). Distributed Arrays Partition large arrays across the ...
function T = isMultipleRow(A) nA = height(A); T = false(nA, 1); [S, idx] = sortrows(A); m = [false; ~any(diff(S, 1, 1), 2)]; if any(m) % Any repeated elements found: ini = strfind(m.', [false, true]); m(ini) = true; % Mark 1st occurence in addition ...
利用unique函数可以将数组或矩阵中重复元素去掉。 function qiqing34( ) clc; data = [1, 2, 3, 1, 2]; disp('data:'); disp(data); disp('unique(data):'); disp(unique(data)); Pnames = {'黑龙江省' '吉林省' '辽宁省' '甘肃省' ...
利用unique函数时可以根据需要添加选项,这里列举了几个选项的结果。 function qiqing35( ) clc; data = [1, 1, 2, 3]; disp(data); disp(unique(data)); disp(unique(data,'rows')); Pnames = {'黑龙江省' '内蒙古自治区' '新疆维吾尔自治区' ...
unique function in matlabIt's hardly pointless, and it was the addition of a new option to an existing function which is perfectly fine.Code written for R2010auniqueworks exactly the same in R2012ait and then index back into the original.
在编程中,unique 函数通常用于从数组或列表中删除重复的元素。尽管许多编程语言内置了 unique 函数(如 MATLAB),但在一些情况下,你可能需要手动实现类似的功能或者在不同的编程语言中找到替代方法。以下是一些常见编程语言中实现唯一元素列表的替代方法: Python Python 中没有内置的 unique 函数,但你可以使用集合(set)...
