matdeintrlv
Restore ordering of symbols by filling matrix by columns and emptying it by rows
Syntax
deintrlvd = matdeintrlv(data,Nrows,Ncols)
Description
deintrlvd = matdeintrlv(data,Nrows,Ncols) rearranges
the elements in data by filling a temporary matrix
with the elements column by column and then sending the matrix contents,
row by row, to the output. Nrows and Ncols are
the dimensions of the temporary matrix. If data is
a vector, it must have Nrows*Ncols elements. If data is
a matrix with multiple rows and columns, data must
have Nrows*Ncols rows and the function processes
the columns independently.
To use this function as an inverse of the matintrlv function,
use the same Nrows and Ncols inputs
in both functions. In that case, the two functions are inverses in
the sense that applying matintrlv followed by matdeintrlv leaves
data unchanged.
Examples
The code below illustrates the inverse relationship between matintrlv and matdeintrlv.
Nrows = 2; Ncols = 3; data = [1 2 3 4 5 6; 2 4 6 8 10 12]'; a = matintrlv(data,Nrows,Ncols); % Interleave. b = matdeintrlv(a,Nrows,Ncols) % Deinterleave.
The output below shows that b is the same
as data.
b =
1 2
2 4
3 6
4 8
5 10
6 12
