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 ...
This transformation introduces round-off differences in y. Get x = (1:6)'*pi; y = 10.^log10(x); Verify that x and y are not identical by taking the difference. Get x-y ans = 6×1 10-14× 0.0444 0 0 0 0 -0.3553 Use unique to find the unique elements in the ...
There are two ways to modify elements in a cell array: cell indexing and content indexing. 使用单元索引来修改元胞数组,需要借助小括号()来实现。例如将上述cell数组中的第二行第一列的文本“Hello”,修改为“Good bye”。 To modify a cell array using cell indexes, you need to use parentheses ()...
IfAis a matrix or array, thenA(:) = C(ic). IfAis a table, or if the'rows'option is specified, thenA = C(ic,:). Tips Useuniquetolto find unique floating-point numbers using a tolerance. To find unique rows in tables or timetables with respect to a subset of variables, you can...

Sort 3-D Array Copy Code Copy Command Create a 2-by-2-by-2 array and sort its elements in ascending order along the third dimension. Get A(:,:,1) = [2 3; 1 6]; A(:,:,2) = [-1 9; 0 12]; A A = A(:,:,1) = 2 3 1 6 A(:,:,2) = -1 9 0 12 Get B...
P = uniqueperms(V) returns all unique permutations of the N elements in the vector V. P is an array with M rows (see below) and each row of P is unique. The rows are in lexicographic order. V can be a numeric array, or cell array of strings. Example: uniqueperms([4 2 1 2...
