This function computes the moments and the rotations using slope deflection method(SDM).

1	SDM2FSCSuper(InputMatrix)

InputMatrix

The matrix with parameter values for SDM2FSC().

Given the span length, magnitude of load, type of load, point of action, Young's Modulus, and interia, the function computes the moments and the rotations using SDM.

Moments and Rotations

The possible values for Typeof1 and Typeof2 are UDL/PL/TDLS/TDLE.
The possible value for CMomentDirection is "C" if clock-wise.
UDL:Uniformly Distributed Load
PL:Point Load
TDLS:Triangular Distributed Load(the maximum value is at the start, see http://www.abzwater.com/sdm)
TDLE:Triangular Distributed Load(the maximum value is at the end, see http://www.abzwater.com/sdm )
