my question is what is wrong with my code, the results should be in the first picture not the second.

D=zeros(6);
for row=1:6
for col=1:6
if col>row %upper right corner
D(row,col)=0
else if col==row %diagonal
D(row,col)=0
else if row>col % bottom left corner
if mod(row,2) ==0 && col==1
D(row,1)= row-1
if mod(row,2)==0 && mod(col,2) ==1 && col>=3
D(row,col)= (row-1)*2
if mod(row,2) ==1 && mod(col,2) ==0
D(row,col)= (row-1)*2
end
end
end
end
end
end
end
end

Hi jana,
the problem is that the if statements
if mod(row,2)==0 && mod(col,2) ==1 && col>=3 % (b)
and
if mod(row,2) ==1 && mod(col,2) ==0 % (c)
are contained within
if mod(row,2) ==0 && col==1 % (a)
.......
.......
end
and their conditions conflict with (a) so they never are implemented. If for both (b) and (c) you change 'if' to 'elseif' and then get rid of two suddenly extraneous end statements at the end, it works.

hey, I just solved an hour ago
D=zeros(50);
for row=1:51
for col=1:51
if col>row %upper right corner
D(row,col)=0
else if col==row %diagonal
D(row,col)=0
end
end
if row>col % bottom left corner
if mod(row,2) ==0 && col==1
D(row,1)= row-1
end
if mod(row,2)==0 && mod(col,2) ==1 && col>2
D(row,col)= (row-1)*2
end
if mod(row,2) ==1 && mod(col,2) ==0
D(row,col)= (row-1)*2
end
end
end
end

Hi jana, I forgot to mention that there is no need to do the for loops that set the upper right corner to zero, since your preallocation of D made them zero already.
