can some one help me to understand this

Name Size Bytes Class Attributes

A 1x4x2 64 double

B 1x4x2 64 double

C 5x2x6 480 double

D 3x2x6 288 double


E = A+B+C+D

its comes with error
why the error is? and how I can check the problem and how to solve this

Thanks

In the subject you talk about vertcat while in the example you're summing stuff...state precisely what you want to obtain.

Hi, are you really trying to add these arrays as you suggest with
E = A+B+C+D ? I'm asking because your post has "vertcat error" in the subject line, but you should be getting an array dimension mismatch error.

Actually the matlab says the error is on line where I am adding all.

May be its coming from somewhere else. I do not know how to play with matrix yet.


I need practice i think.

Anyway Thanks for ur attention.

You may find useful the getting started guide:
http://www.mathworks.com/access/helpdesk/help/techdoc/learn_matlab/bqr_2pl.html

In general you can't do:
[1,2] + [1,2,3] because it operates element-wise.
You can gain flexibility with bsxfun to have 1+1 1+2 1+3 2+1 2+2 2+3
