Need Matlab code to plot ER, EZ and EQ in cylindrical coordinates

please i need help in matlab

my problem is

i have ER and EZ and EQ in (R,Q)coordinates (cylindrecal coordinates)

all these feild componantes are one dimension array in R only

i.e. ER(R),EQ(R)and EZ(R)

and for all Q no change with Q

i.e. ER(R,Q1)=ER(R,Q2) for all Q

please i need a code in matlab to plot these fields in (R,Q) coordenates

let R=0:1/80:1

thanks
