Generates double precision values from multivariate normal distribution using a reference vector previously set-up via a call to drandmultinormalreference.

Parameters:
  • n[in] Number of values to generate, n > 0

  • ref[in] Reference vector, generated by a call to drandmultinormalreference

  • state[inout] On Entry: Current state of the base generator being used. state must have first been initialized with a call to drandinitialize On Exit: State of generator after n- values are generated

  • x[out] Vector of n- values from a multivariate normal distribution, x(ldx,M)

  • ldx[in] Lead dimension of x as defined in the calling routine, ldx >= n

  • info[out]

    Error code

    1 = Everything OK, but reference vector not set up, due to lref being -1 on entry

    0 = Everything OK

    -1 to -5 = Error in parameter, abs(info)
