Change index in matrix

Question

I'm trying to change the matrix index, by storing values, but I'm not quiet sure how to do it.

I have a matrix imported from Excel, where the values in the first row and column indicating a week number and a zip code. So when I call the function in command window, I would like to be able to write week number and zip code as parameters, instead of the matrix index. Is that possible? And how?

Thank you

You can probably do it with a function like this:

function value = GetValue(matrix, date, zipcode)
    r = find(matrix(:, 1) == date);
    c = find(matrix(1, :) == zipcode);
    value = matrix(r,c);
end

Thanks, but what if I wish to use While to run through the column with zip codes, and find the matrix index for the zip code I type in my call. Would that be possible and how? Thank you – Nanna Larsen Jun 10 '13 at 19:18
@NannaLarsen I don't understand your question I'm afraid. With this function you can just enter a date and a zip code and pull out the relevant cell? Is that not what you are trying to do? – Dan Jun 11 '13 at 06:49
