intrlvd = intrlv(data,elements)
intrlvd = intrlv(data,elements) rearranges the elements of data without repeating or omitting any elements. If data is a length-N vector or an N-row matrix, elements is a length-N vector that permutes the integers from 1 to N. The sequence in elements is the sequence in which elements from data or its columns appear in intrlvd. If data is a matrix with multiple rows and columns, the function processes the columns independently.
The command below rearranges the elements of a vector. Your output might differ because the permutation vector is random in this example.
p = randperm(10); % Permutation vector
a = intrlv(10:10:100,p)The output is below.
a =
10 90 60 30 50 80 100 20 70 40
The command below rearranges each of two columns of a matrix.
b = intrlv([.1 .2 .3 .4 .5; .2 .4 .6 .8 1]',[2 4 3 5 1])
b =
0.2000 0.4000
0.4000 0.8000
0.3000 0.6000
0.5000 1.0000
0.1000 0.2000
