my matrix 'GO' has two more variables 'd' and 'e ' which should be held constant throughout the feedback command so that i can use the resulting equation to optimize using particleswarm and find the best values of d and e
GO =
[ (((68771*e)/2500 + (68771*d)/(2500*s))*((6524382794570147*s^2)/1152921504606846976 + (2603*s)/50000 + 281/62500))/(s^3 + (9357*s^2)/1000 + (557*s)/250 + 6147/100000) - (((6159367846211619*s)/9223372036854775808 + 438974862879057/144115188075855872)*((97727*e)/10000 + (97727*d)/(10000*s)))/(s^3 + (9357*s^2)/1000 + (557*s)/250 + 6147/100000) - (1736876246690215*((26917*e)/2500 + (26917*d)/(2500*s)))/(576460752303423488*(s^3 + (9357*s^2)/1000 + (557*s)/250 + 6147/100000)), (1736876246690215*((68771*e)/2500 + (68771*d)/(2500*s)))/(576460752303423488*(s^3 + (9357*s^2)/1000 + (557*s)/250 + 6147/100000)) - (((26917*e)/2500 + (26917*d)/(2500*s))*((6524382794570147*s^2)/1152921504606846976 + (1357*s)/50000 + 4670485015162337/1152921504606846976))/(s^3 + (9357*s^2)/1000 + (557*s)/250 + 6147/100000) - (((97727*e)/10000 + (97727*d)/(10000*s))*((1277*s)/50000 + 4632438605510311/1152921504606846976))/(s^3 + (9357*s^2)/1000 + (557*s)/250 + 6147/100000)]

looks big because it is in fractional form ,it is a 2*2 matrix
where my my measuring element is [1 1 ;1 1]
i need to find negative feed back for these two , how to find it
