Hello everyone, I meet a problem with my code. when I run this code below, I get this error :
Error using svd Input to SVD must not contain NaN or Inf.
Error in fxy_I2_5Ddamp_nx_ny>P_RD (line ....)
[U,S,V] = svd(din);
How do I solve this problem ? Thanks.
function [dout]=P_RD(din,N,K)
[U,S,V] = svd(din);
s = SoftTh(diag(S), 2);
j=1:N
S=diag(s);
for j=1:N
S(j,j)=S(j,j)*(1-S(N+1,N+1)^K/S(j,j)^K);
end
dout=U(:,1:N)*S(1:N,1:N)*(V(:,1:N)');
return

Hello,
According to the error, it could be seen that the matrix "din" contain "NaN" or "Inf". To solve your problem, you need to check why do you have NaN or Inf in the matrix "din".

Run any(any(isnan(din))) and any(any(isinf(din))). If the output is 1 it means your matrix din has an infinity value or a not a number value. This is causing the svd function to error out.

I was able to create a sset sys, went to make it again with the same data and got this error about the NaN and Inf. I tried your suggestion (thank you!) and have 0 for both NaN and Inf. Yet still getting the same error?

I dont get a numeric answer. I get
sparse logical
All zero sparse: 1×1
