How to remove Zeros in the array

r=5;

for x=1:r

for y=1:x

A(x,y)=x.*y;

end

end

In this code I want Matlab to print the multiplication table using a nested for loop. The for loop works but does not print what I want.

I want it to look something like this:

1

2 4

3 6 9

4 8 12 16

5 10 15 20 25

How do I get Matlab to not place 0s in the empty spaces?

Try this:

r=5;
for row=1:r
    for col=1:row
        A(row,col)=row.*col;
    end
	fprintf('%4d ', A(row, 1:row))
	fprintf('\n');
end
A

You'll see this:

1

2 4

3 6 9

4 8 12 16

5 10 15 20 25

A =

1 0 0 0 0

2 4 0 0 0

3 6 9 0 0

4 8 12 16 0

5 10 15 20 25
