For loop for matrix with increasing numbers

I'm trying to use a for loop to create a 7x8 matrix that increases by 4 for each number (starting at 1).

So far I have something that goes

for 
k = 1:8 
a(k)=4*k;
end

just to create the first row... how would I go about adding more rows that keep adding increasing elements?

Try this:

theNumber = 1;
for col = 1 : 8
    for row = 1 : 7
        a(row, col) = theNumber;
        theNumber = theNumber + 4;
    end
end

I was going for increasing in the rows so I just switched the row/column. i.e.

 theNumber = 1;
for row = 1:7
    for col = 1:8
        a(row, col) = theNumber;
        theNumber = theNumber + 4;
    end
end

Thanks for your help!! :)
