Specify LMI terms when lhs and rhs have different block partitions

Hello, I'm trying to specify a LMI term via lmiterm function. The left hand side (lhs) and the right hand side (rhs) in my question have different block structure. For example, consider

where , are constant matrices, , and are variables.

I set the lhs by the following code:

M=rand(5,3);E=rand(2,3); % take random M and E for example
setlmis([]);
X1=lmivar(1,[2 1]);X2=lmivar(1,[3 1]);
r=lmivar(1,[1 1]);

lmiterm([1 1 1 X1],1,1); % first block
lmiterm([1 2 2 X2],1,1); % second block
lmiterm([1 0 0 0],M); % outer factor M

How can I specify the rhs?

I tried

lmiterm([-1 1 1 r],E',E);

It returned a error: rhs of LMI #1, block (1,1): term dimensions incompatible with other terms in row #1 or column #1.

I also tried

lmiterm([-1 0 0 r],E);

The error was: LMI #1: the outer factors have incompatible dimensions.

I appreciate it if anyone can hlep me out. Thanks in advance!
