plot selective columns eliminating few

Read the questions posted on this topic, couldn't find something relatively closer. I have a matrix of 512x40, from this, I want to plot, 1-28 columns and from 29, I want only odd column's to be plotted. Any help is appreciated.

 A = Data(:,29:2:end);

 The above one just plots odd columns from 29-end. How do I include 1-28 columns in this?

One way would be manually defining the column/row numbers like a = (:,[1,2,3,4,5]); But this is lengthy. Is there any alternate method?

 A = Data(:,[1:28,29:2:end]);
