how to rectify the index must be a positive integer or logical error?

I have to rectify the Error using Horzcat command.

domr=[6 7];

domg=[3 4];

domb=[2 ];

dom=horz(domr,domg,domb);

Then Decoding stage i got Error in ??? Attempted to access dompol1(-3,:); index must be a positive integer or logical.

Error in ==> DEIMGC at 12 D1=dompol1(fraco(4),:);

Error occurring in the following function arguemnts.....

[cimg1r]=deimgc(vqcode7r,dompool3r,gsize,scale);

[cimg1g]=deimgc(vqcode7g,dompool3g,gsize,scale);

[cimg1b]=deimgc(vqcode7b,dompool3b,gsize,scale);

how can I pass the negative values in this program or how to rectify the Negative Error?

You are asking for horzcat, but you call horz. The latter could be FEX: horz, but this is not clear.

Perhaps you want this:

domr = [6 7];
domg = [3 4];
domb = [2 ];
dom  = horzcat(domr, domg, domb);
% or equivalent:
dom = [domr, domg, domb];

Ok Sir I accept that concatenation.

Now I want to Error rectification of Attempted to access dompol1(-3,:); index must be a positive integer or logical.

Error in ==> DEIMGC at 12 D1=dompol1(fraco(4),:);

Error occurring in the following function arguemnts.....

[cimg1r]=deimgc(vqcode7r,dompool3r,gsize,scale);

[cimg1g]=deimgc(vqcode7g,dompool3g,gsize,scale);

[cimg1b]=deimgc(vqcode7b,dompool3b,gsize,scale);

how can I pass the negative values in this program or how to rectify the Negative Error? or how can i convert the negative value to positive value?
