Solve matrix reshape error

Question

0 个投票

Hello,

I have a 6 x 1200 matrix. For each row, I want to sum columns 1:600 and 601:1200 using the code below.

sum_dGwdt_gwd = squeeze(sum(reshape(sum_dGwdt_gwd,size(sum_dGwdt_gwd,1),600,[]),2)/50); 

However, I keep getting the following error.

Error using reshape
Product of known dimensions, 3600, not divisible into total number of elements, 6.

It would be helpful if anyone can point out what I'm doing wrong.

Thank you.

A = rand(6,1200) ; 
iwant = [sum(A(:,1:600),2) sum(A(:,601:end),2)] ;

Thanks @KSSV, but I'm getting an error for your code above. Anyways, I have solved the problem on my own. Thank you for your input.

Index in position 2 exceeds array bounds (must not exceed 1).
