Hi all,

I'm trying to solve an lmi problem with matlab toolbox. When I insert a matrix in lmi term in line 102 program ( the mfile is attached)

an error occure by this statement:

"Error using lmiterm (line 274)

lhs of LMI #1, block (4,4): term dimensions incompatible with other

terms in row #4 or column #4

Error in controllorfilecode (line 102)

lmiterm([1 4 4 0],1*Po);"

but when i checked the dimensions of matrix Po, I found there is no problem, for this reseon, instead of inserting Po, I insert a zero matrix that its dimensions is equal to Po, The lmi run correctly.

I will apreciate if help me.
