Shear & Bending Moment diagrams

Hello everyone,

Are there any simple ways to plot shear and moment diagrams for a 2D-Frame with variables inputs? ----------------------------- These are the inputs node=[0 0; 8000 0; 13000 0; ]; conn=[ 1 2; 2 3; ]; supports=[1 1 1;0 1 0;0 0 0]; A=[6000 ; 4000 ]; E=[200 ; 200 ]; I=[200000000;50000000]; Nforces=[0 0 0 ;0 0 0;3.535 -3.535 0]; ----------------- Thanks ,
