Function File: [Reactions, Displacements, MemF] = SolveFrame(joints, members, nodeloads, dist, point)

Solves a 2D frame with the matrix displacement method for the following input parameters:

joints = [x , y, constraints ; ...]

constraints=[x , y, rotation] free=0, supported=1

members = [nodeN, nodeF, E, I, A; ...]

nodeloads = [node, Fx, Fy, Mz; ...]

loads on members:

dist = [membernum,FxN,FyN,FxF,FyF,a,b,local ; ...] for distributed loads where FxN and FyN are the loads on distance a from the near node (same with far node and distance b) local=1 if loads are on local axis, 0 if global

point = [membernum,Fx,Fy,a,local; ...] where Fx and Fy are the loads on distance a from the node near local=1 if loads are on local axis, 0 if global

Output is formated as follows (rownumber corresponds to node or member number):

Reactions = [Fx,Fy,Mz;...] where NaN if it was a non supported dof

Displacements = [x,y,rotation;...]

MemF = [FxN, FyN, MzN, FxF, FyF, MzF; ...]
