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

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

I will get number of matrices according to variable as element in the matrix?

What does that mean. Can you explain that with a short example, let us say a 2x2 cell array

A={[1 2],[3 4];[5 6],[7 8]}

Sir, I have

K=
[k1,    0,                                 -k1,                                   -k1/2]
[     0,   k2,                                 -k2,                                    k2/2]
[   -k1,  -k2,              k1 + k2 + k3 + k4 + k5,     k1/2 - k2/2 + (9*k3)/10 - (9*k5)/10]
[ -k1/2, k2/2, k1/2 - k2/2 + (9*k3)/10 - (9*k5)/10, k1/4 + k2/4 + (81*k3)/100 + (81*k5)/100].

In this matrix I want to vary k1, k2, k3, k4 and k5. If I change these values, I should get different K matrix. In short k1, k2, k3, k4 and k5 are the vectors.

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

Same example I am carrying forward. Lets assume k1=[1 2 3 4 5];k2=[1 2 3 4 5] A=[112 2+k1;2*k1+k2 12]; What would be the output of A?

[Azzi Abdelmalek]

Why are you asking? just test your code in Matlab command, and you will see the result.

k1=[1 2 3 4 5];
k2=[1 2 3 4 5]; 
A=[112 2+k1;2*k1+k2 12]

Thank u sir...Earlier there was an error.
