    take home exam urgent latex help!!!

    hi! i don't know anything about latex, but i need pictures a matrix:

    it is a tridiagonal matrix with (1-2lambda) on the main diagonal (except for the last row where it's 1-lambda) and lambdas above and below:

    [(1-2*lambda) lambda 0 0 .................................. 0]

    [lambda (1-2*lambda) lambda 0 0 .................... 0]

    [ 0 lambda (1-2*lambda) lambda 0 ... 0 ]

    [ 0 \ \ \ 0 ]

    ...

    [ 0 ........................................... lambda (1-lambda)]



    please help, can't focus on actual problems because of these silly things. any format will do: ,jpg, .png, .pdf, ... anything or just the latex code.

    Welcome to PF fluffy,

    Google for 'latex arrays' and you should find a number of appropriate tutorials.
