/**
    Purpose
    -------

    magma_cprint prints a matrix that is located on the CPU host.
    The output is intended to be Matlab compatible, to be useful in debugging.

    Arguments
    ---------

    @param[in]
    m       INTEGER
            The number of rows of the matrix A.  M >= 0.

    @param[in]
    n       INTEGER
            The number of columns of the matrix A.  N >= 0.

    @param[in]
    A       COMPLEX array, dimension (LDA,N), on the CPU host.
            The M-by-N matrix to be printed.

    @param[in]
    lda     INTEGER
            The leading dimension of the array A.  LDA >= max(1,M).
