matintrlv

Reorder symbols by filling matrix by rows and emptying it by columns

Syntax

intrlvd = matintrlv(data,Nrows,Ncols)

Description

intrlvd = matintrlv(data,Nrows,Ncols) rearranges the elements in data by filling a temporary matrix with the elements row by row and then sending the matrix contents, column by column, 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.

Examples

Apply Matrix Interleaving to Reorder Input Matrix

Use the matintrlv function to reorder the elements filling matrix by rows and emptying it by columns.

To form the first column of the output, the function creates the temporary 2-by-3 matrix [1 2 3; 4 5 6]. Then the function reads down each column of the temporary matrix to get [1 4 2 5 3 6].

b = matintrlv([1 2 3 4 5 6; 2 4 6 8 10 12]',2,3)

b = 6×2

     1     2
     4     8
     2     4
     5    10
     3     6
     6    12

To form the first column of the output, the function creates the temporary 3-by-2 matrix [1 2; 3 4; 5 6]. Then the function reads down each column of the temporary matrix to get [1 3 5 2 4 6].

b = matintrlv([1 2 3 4 5 6; 2 4 6 8 10 12]',3,2)

b = 6×2

     1     2
     3     6
     5    10
     2     4
     4     8
     6    12
