How do i find the matrix A,B1,C1,C2​,D11,D12,D​21,D22 for hinf problem?

A=[Ag 0 0 0 0

0 Ab 0 0 0

0 0 Ap 0 0

-Bw*Cg1 Bwp*Cb 0 Aw 0

-Bwp*Cg1 0 Bwp*Cp 0 Awp]

I dont know how to concatanate in order to obtain the A matrix. I specify that i have all the matrix:Ag,Ab,Ap etc. Zeros needs to have their specific dimensions.g represents the nominal matrix, beta for dutch role, p for roll. W represent the weighting matrix.

What are the values of the variables you're using?

This are the matrix. But sincerely i dont know how to use them in roder to obtain the matrices for hinf problem in matlab.

I have no clue what problem you are refering to, but as your variables are matrices, instead of scalars, the definition you stated in your initial question is not valid Matlab syntax.
