What is the result of CD(1:8:8*16)=ciphertext ? Not able to interpret this.

Imagine that CD is an array that is 8 x 16. Then that operation would be the same as storing values to the entire first row.

It simply replaces elements 1,9,17, 25, ..., 121 of CD by the elements of ciphertext. Since that's 16 elements of CD that are replaced, if ciphertext does not have exactly 16 elements, the line is an error.
If CD is an 8x16 matrix, then as Walter commented, this replace the first row of CD. And in that case CD(1, :) = ciphertext would have been clearer.
