MATLAB: Rearranging matrices horizontally rather than vertically

rearrange matrix

I want to reshape this matrix but the following command does the rearrangement not properly.
b=(rand(30,1)).'
c = reshape(b,[3,10])
i want to rearrange in the following manner
b= 4 1 3 5 7 1 2 3 5 6 …… 2 3 4
c= 4 1 3 5 7 1 2 3 5 6 (10 columns)
My command rearranges c as 4 5 2 ….
how can i change this?

This is because the index order in a matrix is along columns. I'm not sure your command does what you say. Anyway
 b= [4 1 3 5 7 1 2 3 5 6 1 2 ];
 c = reshape(b,[3,4]);
gives
 c =
     4     5     2     6
     1     7     3     1
     3     1     5     2
while
 c = reshape(b,[4,3])'
gives
 c =
     4     1     3     5
     7     1     2     3
     5     6     1     2
Probably the random numbers are only for the sake of example. If this is not the case, why don't you simply write
 b = rand(3,10);
?
