I am completely new to Mathematics. I am doing an exercise which requires me to use Table
to make a $10 \times 10$ matrix with numbers $1,2,...,10$ on the diagonal and $1$ in the upper diagonal entries and with $0$ in the lower diagonal matrix.
I have been able to generate the diagonal command along with the upper diagonal command (using If
) but that yields $1$ in the lower diagonals also.
Can anybody help me with this code?
If
s or aWhich
can help here... $\endgroup$ – Henrik Schumacher Apr 25 '18 at 12:44
