Matlab call to TX quadrature calibration.

My test bench hardware is a ZED board and AD-FMCOMMS4-EBZ with the AD-9364.  It uses Matlab with the IIO drivers and has no problem showing the complex base band output when up/down converting to 1 GHz.  When a pure 10 kHz sine wave is applied, there is a -10 kHz component down about 35 dB from the +10 kHz component.  What function is called in Matlab to perform TX quadrature calibration so that this signal can be minimized?  There is reference in UG-673 to ad9361_tx_quad_calib. Where to find a list of Matlab driver functions?
