Hello,
Excuse me. I have a simple question about using FwdInvToolbox, in which there 
is an example, tikhonov-inverse.srn.  
The module that solves the inverse problem by means of Tikhonov 
regularization is SolveInverseProblemWithTikhonov, in which I find that there 
is a linear system 
Ax=b.
After importing it into Matlab, I find that A is a matrix of the size 
771-by-128. The size of this linear system is small.
I am interested in this linear system, and want to test a larger linear 
system, for example, the matrix A with the size of several thousands. My 
question is how I can get such larger linear system.
I think I need to use finer grids and change the three input data files:
for_mat_128.mat
epi_pot_128_fr_170to190.mat
25feb97_sock_closed.fld
But how to generate these files? Can anybody here help me? Thank you very 
much in advance.
Best regards,
Hua
