Error :Assignment has more non-singleton rhs dimensions than non-singleton subscripts

I got this problem " Assignment has more non-singleton rhs dimensions than non-singleton subscripts " My code is:

 v(m,i,j,k,l)=(-1*ones(m,i,j,k,l) + 2*rand(m,i,j,k,l))+rand*(gbest(m,i,j,k,l)-p(m,i,j,k,l));

Thank you so much!

Answer 1

[Walter Roberson]

ones(m,i,j,k,l) results in an m x i x j x k x l array. You compute something with that array size, and try to store the array result into the single scalar location v(m,i,j,k,l)

Answer 2

[Amogh Maharudra Gadagi]

residual_2(i,j)=0.25*(residual(2*i-2,2*j-2)+residual(2*i-2,2*j-1)+residual(2*i-1,2*j-2)+residual(2*i-1,2*j-1));

How can i get rid of this error
