creating a mapping matrix

. Specify the components of the deformation tensor (matrix) F and use it to compute strain tensor E. The tensor F is the mapping matrix. We can use it to compute the deformed location of points that we identify in the undeformed configuration (e.g., the vertices of the initial square of material).

trying to create the F matrix and not sure how

[A C]

% given

X = [1.5;0]

b = [1.75; 0.4]

% A*X = b

A = b/X

Answer 1

[A C]

% given
X = [1.5;0]
b = [1.75; 0.4]
% A*X = b
A = b/X
