MATLAB: For loop for matrix with increasing numbers

Question

I'm trying to use a for loop to create a 7×8 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?

Answer 1

Try this:

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