The values of the "a" and "c" properties must be matrices with the same number of columns.

A=[-0.0895 -0.286 0;-0.0439 -0.272 0;0 1 0]

[KALYAN ACHARJYA]

Error clearly stated that A and c state-space matrices to be same number of columns to avoid this error.

A=[-0.0895 -0.286 0;-0.0439 -0.272 0;0 1 0]
b=[0.0145;-0.0122;0]
c=randi(5,[2,3]);  % Changed here for test
d=[0]
sys=ss(A,b,c,d)
