How to solve the elements are different between X0 and H in quadprog

In my Simulink model, the H[10x10],x_start[10x10], but

'The number of rows and columns in H must be the same as the number of elements of X0.'

"[X,~,exitflag]=quadprog(H,f,A_cons,b_cons,[],[],lb,ub,x_start,options)"

The initial value parameter, x_start in this context, must be a vector .
