 cat(3,A,B)

i have used the above syntax..but now my matrix becomes 128*128*25..but i need it as 128*128*24..

[Matt J]

How can you "concatenate" two arrays without the result being bigger than the input arrays? Please describe better what it is you want to do.

[Benitta glara]

as i have to give the resultant matrix into the classifier i need it as 128*128*24 because the scale factor of my classifier is 24

[Matt J]

That wasn't my question.

[Benitta glara]

ok...now i had another doubt..iam using two class svm classifier..in that my scale factor is 24..how can I change that..

[Matt J]

Best to ask that in a separate post, with a title that will catch the eye of machine learning specialists.

Answer 2

[Azzi Abdelmalek]

your first matrix A size is 128*128*24. If you concatenate any matrix to A the result size, obviously will change! why are you expecting the final size to be the same? have you read Matt's comment?

[Azzi Abdelmalek]

Unless you want to replace one matrix by another, in this case use for example

A=rand(128,128,4);B=rand(128,128)
A(:,:,1)=B;
