Help with matrix in m file

  1. Dec 5, 2007 #1
    I'm trying to write an m-file in matlab that can count how many data point in a vector are zero, how many are 1, etc. I can call the vector and get the length, max and min values, but I also need to be able to call each element seperatly and I can't figure out how to do this. I've been playing around and this is what i have:

    function len (A)
    N= length(A);
    M =max(A);
    m=min(A);
    S=0;
    for i=1:N

    if
    A[i,1]=0;
    S=S+1;
    end



    len=N
    MAX =M
    MIN=m
    zero=S

    But it says expression (A=[i,1]=0) is incomplete. I've tried a few other expressions but none work. Any help is appreciated.

    When you reference an element in Matlab, you use parenthesis, if I remember correctly. So you'd need to reference A(i,1).
