Abstract: The duality between two dimensional string theory and matrix integral has been checked in various aspects. In this talk I will talk about the N=1 supersymmetric extension to the complex Liouville string. By gauging the different worldsheet supersymmetries we can get two different types of SCLS. And we call that SCLS and \widehat{SCLS}. The 3-point amplitude of SCLS is exactly the same as the bosonic case, which implies the dual matrix integral is the same as the bosonic case. And \widehat{SCLS} gives different amplitudes. We can propose the dual matrix integrals and then calculate the 4-point amplitudes using matrix integral. They satisfies the correct analytic properties and higher equation of motions. I will give a numerical check to part of the 4-point amplitudes, which further implies relationship between the matrix integrals and the 2d superstring theory.
