Hello,
I am trying to limit the size of a 10x10 matrix depending on a given variable, for example (n). The 10x10 matrix is the basic matrix with all numbers in it.
(n) is going to be any number from 0 to 10. for instance, if I put n=6, the matrix is going to be 6x6 with its numbers coming from the 10x10 matrix.
To be more clear, if I have this matrix which is 10x10 ( the basic matrix) with all its variables are given:
K=[ k1+k2 -k2 0 0 0 0 0 0 0 0 ;
-k2 k2+k3 -k3 0 0 0 0 0 0 0 ;
0 -k3 k3+k4 -k4 0 0 0 0 0 0 ;
0 0 -k4 k4+k5 -k5 0 0 0 0 0 ;
0 0 0 -k5 k5+k6 -k6 0 0 0 0 ;
0 0 0 0 -k6 k6+k7 -k7 0 0 0 ;
0 0 0 0 0 -k7 k7+k8 -k8 0 0 ;
0 0 0 0 0 0 -k8 k8+k9 -k9 0 ;
0 0 0 0 0 0 0 -k9 k9+k10 -k10 ;
0 0 0 0 0 0 0 0 -k10 k10]
If I put n=3, the matrix will be 3x3 coming from the 10x10 matrix (the basic matrix):
K=[ k1+k2 -k2 0 ;
-k2 k2+k3 -k3
0 -k3 k3+k4]
Thank you in advance.
