I am trying to write a matlab program to create a matrice column by column and whose entries are columnwise successive integers, how would I do this? Some light explanation would help me in the right direction toward creating other matrices.

You need to be a little clearer...
Do you mean this?
A = [ 1 2 3 4
1 2 3 4
1 2 3 4 ];
Or this?
A = [ 1 1 1 1
2 2 2 2
3 3 3 3 ];
Or this?
A = [ 1 4 7 10
2 5 8 11
3 6 9 12 ];
[edit]
Righto. Well, you already know how to generate a vector of consecutive values with the colon-operator...
A = 1:12;
It's just that it's the wrong shape.
Since you need to do some of this yourself, have a look at the MatLab command reshape.
doc reshape
And I'm sure you can figure out the rest. You just need to work out how many values to generate, given your dimensions.
