I don't quite understand how to pass multidimentional arrays to a function.
I am using two-dimentional arrays right now.  I read somewhere that you must
specify the column subscript, but not the row subscript.  The problem is, I
have several arrays (or tables) of different sizes, and I'm trying to pass
them to a lookup function.
For example:

float table_lookup(float table[][], float reference)
{
    float tableValue
    int stop, pointer, xRef, yRef;
    for (stop = 0, pointer = 1; stop != 1; pointer++)
    {
        if (reference == table[pointer][0])
        {
        yRef = pointer;
        stop = 1;
        }
    }
    for (stop = 0, pointer = 1; stop != 1; pointer++)
    {
        if (reference == table[0][pointer])
        {
        xRef = pointer;
        stop = 1;
        }
    }
    return tableValue[yRef][xRef];
}

When I compile this it gives me the error: "Arithmetic on pointer to an
incomplete type".  I know that "float table[][]" is wrong, but I don't know
what to put here.
Can anybody help?
