    Purpose   
    =======   

    ILADLR scans A for its last non-zero row.   

    Arguments   
    =========   

    M       (input) INTEGER   
            The number of rows of the matrix A.   

    N       (input) INTEGER   
            The number of columns of the matrix A.   

    A       (input) DOUBLE PRECISION array, dimension (LDA,N)   
            The m by n matrix A.   

    LDA     (input) INTEGER   
            The leading dimension of the array A. LDA >= max(1,M).   

    =====================================================================   


       Quick test for the common case where one corner is non-zero.
