How can I resolve the following index issue? Index in position 2 exceeds array bounds. Index must not exceed 4.

Hi, could anyone please help in resolving the following error message.

Section of the code below:

V=sqrt(P/4)*eye(4,4);

n=sqrt(Pr/trace(H*V*V'*H'+(1/snr)*eye(4,4)));

F=n*eye(4,4);

V1=V(:,1:Mu);

V2=V(:,Mu+1:2*Mu);

V3=V(:,Mu+1:3*Mu);

V4=V(:,Mu+1:4*Mu);

V5=V(:,Mu+1:5*Mu);

And this is the error message:

Index in position 2 exceeds array bounds. Index must not exceed 4.

Error in Naive_convergence (line 11)

V3=V(:,Mu+1:3*Mu);

I need to resolve the indexing of V3 to V5. V1 and V2 are fine.

V has 4 columns. Thus 2*Mu, 3*Mu, 4*Mu and 5*Mu all have to be smaller than 4. Is this the case in your code ?

Yes, that's the case, 4by4. Many thanks

I know that V is 4x4 . But 2*Mu, 3*Mu, 4*Mu and 5*Mu must all be smaller than 4 such that the operations

V1=V(:,1:Mu);
V2=V(:,Mu+1:2*Mu);
V3=V(:,Mu+1:3*Mu);
V4=V(:,Mu+1:4*Mu);
V5=V(:,Mu+1:5*Mu);

don't cause an access violation to V.

This cannot be true since for this, Mu had to be smaller than 1.

The was designed initially for 2 users V1 and V2 and it's working perfectly. I needed to adapt for 5 users so I included V3 to V5 and got the error.
