MATLAB: I have 4X4 stiffness matrix and evey element in matrix is a vecor. How to write ‘for’ loop for this matrix so that I will get number of matrices according to variable as element in the matrix

index

I am trying to vary my matrix of size 4X4. The element in the given matrix are the vectors of 10X1. Please help

I don't see where is the problem. For example:

k1=2;
k2=3;
A=[112 2+k1; 2*k1+k2 12]

%If you want to change A, just change the values of k1 and k2,

k1=4;
k2=10;
A

m=[1 2 3;1 1 1;4 5 8;4 5 8;1 1 1;1 1 1;1 1 1;1 1 1;1 1 1;1 1 1;1 1 1;1 1 1;4 5 8;7 8 5; 47 9 5;7 8 5;5 322 5;7 8 55];

variant 1

[a b n] = unique(m,'rows','first');
[id id] = sort(b);
out1 = a(id,:);

variant 2

[a b n] = unique(m,'rows','first');
[id id] = sort(b);
t = accumarray(n,ones(numel(n),1)) == 1;
a2 = a(id,:);
out2 = a2(t(id),:);

S1 = randi([-1 1],10)
S2 = randi([-1 1],10)

solution

k= S1 + S2
S = (k==2) - (k==-2)

S = (S1 == 1 & S2 == 1) - (S1 == -1 & S2 == -1)

MORE variant

S = (S1 == S2).*S1

S = (S1 == S2).*S2
