MATLAB: Multidimensional Arrays Global stiff matrix

Question

Do anyone know how to make a Multidimensional Arrays GSM, cause I have already make a 2×2 Local Stiff matrix. But I am confuse on make a GSM with for loop. And here is my code for LSM and vaeiables. Thank you

%Step 1 Discretize
%Assign Variables
E = young;
A = area;
L = leng;
F1 = F;
Num_elements = no_e;
l = L/Num_elements ;
K = E*A/l ;
%step 2 Local Behavior
% Form local stiffness Matrixes
LSM = zeros(2, 2, Num_elements);
for x=1: 1: Num_elements
LSM(1,1,x)= K(x,1);
LSM(1,2,x)= -K(x,1);
LSM(2,1,x)= -K(x,1);
LSM(2,2,x)= K(x,1);
end
%Step 3 
%Assemble Global Stiffness Matrix (GSM)

Answer 1

Substitute this portion of your code:

LSM = zeros(2, 2, Num_elements);
for x=1: Num_elements
LSM(1,1)= K;
LSM(1,2)= -K;
LSM(2,1)= -K;
LSM(2,2)= K;
end

With this one:

LSM(1,1)=  K;
LSM(1,2)= -K;
LSM(2,1)= -K;
LSM(2,2)=  K;
