Count unique values in an array編集済み:Azzi Abdelmalek
Unique Values in Array Containing NaNs Copy Code Copy Command Define a vector containing NaN. Get A = [5 5 NaN NaN]; Find the unique values of A. Get C = unique(A) C = 1×3 5 NaN NaN unique treats NaN values as distinct. Unique Elements in Presence of Numerical Error ...
If A is a table or timetable, then unique returns the unique rows in A in sorted order. For timetables, unique takes row times and row values into account when determining whether rows are unique, and sorts the output timetable C by row times. If A is a categorical array, then the ...
It returns the unique values in a sorted vector, and counts of those values are in the same order. - Usage: >> [uniques] = count_unique(largeArray); >> [uniques,numUnique] = count_unique(largeArray); - Example (a rather trivial example): >> a = repmat((1:1000),1000,1); ...
Ran in: matlab.mat Try this — LD = load('matlab.mat'); AA4 = LD.AA4 AA4 =716×2 -3.4100 0 -3.4100 0 -3.4100 0 -3.4100 0 -3.4100 1.0000 -3.4100 0 -3.4100 0 -3.4100 0 -3.4100 1.0000 -3.4100 0 [UAA4,ix1,ix2] = unique(AA4(:,1)); ...
If A is a categorical array, then the sort order is determined by the order of the categories. exampleC = unique(A,setOrder) returns the unique values of A in a specific order. setOrder can be 'sorted' (default) or 'stable'. exampleC...

[counts,centers]=hist(x,unique(x)); 同时我们还可以利用元胞数组对结果进行保存,元胞数组cell cell(1,length(centers)),即返回由空矩阵构成的1*length(centers)的元胞数组。 然后调用循环,我们可以进行结果存储,存放在元胞数组中 for i = 1:length(centers) ...
