Matlab Subscripted assignment dimension mismatch error -

i'm trying perform row multiplication 2 matrices: a , b.

a subscripted assignment dimension mismatch error thrown on line c(1,i) = a(i,:)*b;.

do have syntax error causing dimensions on left , right sides of = sign unequal?

function c = rowproduct(a,b)  [n,m]=size(a); [p,q]=size(b);  c=zeros(1,n);  if( m == p)     i=1:n         c(1,i) = a(i,:)*b;     end else     error('matrix dimension mismatch'); end end 

try replace c(1,i) = a(i,:)*b; c(i,:) = a(i,:)*b;
