Re: Matrices

[Egshiglen Bat-Erdene]

Oh thank you for the help. I found the answer. I will use the ones, substract, eye, use the diag 1:10 and multiply.

Hello

I wanted to ask about matrices. I should do a matrix which is full with 2, but the diagonal is from1 to 10. And A matrix with full zeros, however the diagonal's two sides are -1.

I hope you will help me soon.

show us what you tried.

I agree with Doug, (at least, I assume that he implies this sounds like homework).

Just a hint. the diag function not only retrieves the diagonal.

Once you comprehend that, the tasks are trivial one-liners.
