Radar scattering coefficient plot

Implementing a Matlab code to plot the following Microwave Remote Sensing question problem 8.1 but I keep getting an error message. I attached the code below the problem statement. Theta ranges from 0 to 90 degrees in increments of 0.1, and psi ranges from 90 to 0 degrees in increments of 0.1. I am multiplying the csc(psi)^2 function to the exponential function but I keep getting an error in line 7 shown below the code. The plot shown below the code error is for the exponential function only without being multiplied by the csc(psi)^2 function which is what I need to plot. This is not a polar plot, but a traditional horizontal x and vertical y plot. I can use some guidance to make this work! Thank you!

theta=0:0.1:90;
psi=90:.1:0;
K=csc(psi).^2;
sc=csc(psi).^2*exp(-theta/30);
plot(theta,sc)
xlabel('Theta range');
ylabel('dB');
error message
Error using *
Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix matches the number of
rows in the second matrix. To perform elementwise multiplication, use '.*'.

sc=K.*exp(-theta./30);
polarplot(theta*pi/180,sc) % scattering direction
%('[dB]')
Try in polar plot. This may be better in representing radar problems

You can try with for loop if you want to plot for all psi separately
clc
clc
clear all
close all
theta=0:0.1:90;
psi=90:-0.1:0; % dscrement angle
K=csc(psi).^2;
%K=linspace(0,50,length(theta));
for j = 1:length(theta); for k = 1:length(psi);sc(j,k)=K(k)*exp(-theta(j)/30);end;end
plot(theta,sc) % scattering direction
%('[dB]')
