using subplot with imaginary and real

I want to use subplot for the imagenary part and the real part, is my code correct?

c=3e8; % speed of light m/s

M=50; % 50 pulses

M_samples=M-1;

m_th= 0:1:M_samples; % m_th pulses

v=30; % the radial velocity 30m/s

f_t= 3e9; % frequency of 3.0 GHz

tau= 1e-6; % a pulse width of 1 microsecond

PRF=4e3; % a PRF of 4.0 KHz

R_0=40e3; % an initial range of R0 = 40 km

A=1; % set A to 1

theta=0; % set theta to 0

% calculate

PRI=1/PRF; % find PRI

T = PRI; % T = PRI

f_d=(2*v*f_t)/c; % Calculate the Doppler frequency Hz

m_calc=R_0/(v*T); % calculate m in equation 8.2

t_m= m_calc*T; % claculate the transmited times for the m_th pulse

t_m_2= m_th*T; % estimate the transmited times for the m_th pulse

%

% Equation 8.28

%

y_1=A*exp(i*((2*pi*f_d*t_m)+theta)); % Calculate Equation 8.28 the data y

y_2=A*exp(i*((2*pi*f_d*t_m_2)+theta)); % Estimate Equation 8.28 the data y

% b) Using subplot, plot in subplot(2,1,1) the real portion of y. In subplot(2,1,2), plot the imaginary portion.

% Let the x axis be the time of each pulse number (number pulses from 0 to M?1), in msec.

%

subplot(2,1,1);

plot (m_th,real(y_2));

subplot(2,1,2)

plot(m_th,imag(y_2));

yes in that case, graph real and imaginary part, the only recommendation is that you put 1i instead of i so that it is not confused as a variable

c=3e8;                                 % speed of light m/s

subplot(2,1,2)
plot(m_th,imag(y_2));
