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
The command below rearranges each of two columns of a matrix.
b = matintrlv([1 2 3 4 5 6; 2 4 6 8 10 12]',2,3)
b =
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 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].
