MATLAB: Is there a function to turn ?x2 matrix of coordinates of vertices of a polygon into a ?x4 matrix of coordinates of line segments of that polygon

Yes,

circshift will do the job:

A = [2, 4; 5, 6; 6, 6; 8,5]
B = [2, 4, 5, 6; 5, 6, 6, 6; 6, 6, 8, 5; 8, 5, 2, 4]
% The solution:
C = [A circshift(A,-1)]
% The test:
A =
     2     4
     5     6
     6     6
     8     5
B =
     2     4     5     6
     5     6     6     6
     6     6     8     5
     8     5     2     4
C =
     2     4     5     6
     5     6     6     6
     6     6     8     5
     8     5     2     4

MATLAB: Sum of matrix times scalars

Hold your 3x3 matrices in a 3x3xN array caled T and your scalars in an Nx1 vector called a and do,

result=reshape(T,9,[])*a(:);
result=reshape(result,3,3);
