assemble global stiffness matrix

2 views (last 30 days)
I am trying to assemble a matrix in which I would like to put small matrices into a big one but I don't know how to do that,
I know that I have to define the big matrix first and then show put the small ones inside
for example I have k1=[1 -1; -1 1] , K2=[1 -1; -1 1] and the define bigK in which bigK=zeros(5,5) and in the end I want it to be like bigK = [ 1 0 -1 0 0; -1 0 1 0 0; 0 0 0 0 0; 0 0 0 0 0; 0 0 0 0 0]
in which the small matrices will assemble in diagonal way
how I can do it using a for loop ?
