If I have a list of numbers how can I enter a 1 in a matrix position with the list of numbers

My list of numbers is 1690 numbers long with random numbers

list = [ 1, 2, 3, 4, 6, 7, 9...]

My initial matrix is zeros

initmat = zeros(2387,1);

My goal is to get the number 1 into the correct position in the initial matrix from the list (for instance a 1 in the first, second, fourth, sixth, ninth position etc).

I want my final matrix to look like finalmat, but I the list is too long to do by hand

finalmat = [1, 1, 1, 1, 0, 1, 1, 0, 1...]

[Walter Roberson]

initmat(list) = 1;

Another way of handling this as a single step is

finalmat = accumarray(list(:), 1);

or

finalmat = full( sparse(list, 1, 1) );

Thank you so much, this worked perfectly for me!
