Certainly! Here is the MATLAB code to generate random points in the first quadrant of a circle centered at (0,0):
```matlab
% Defining the radius of the circle
r = 5;
% Generating random points within the first quadrant of the circle
x = rand(1,1000) * r;
y = rand(1,1000) * r;
% Filtering out points outside the circle
inside_circle = (x.^2 + y.^2 <= r^2);
x = x(inside_circle);
y = y(inside_circle);
% Plotting the circle with the generated points
theta = 0:0.01:pi/2;
x_circle = r * cos(theta);
y_circle = r * sin(theta);
plot(x, y, 'o');
hold on;
plot(x_circle, y_circle);
axis equal;
title('Random points within the first quadrant of a circle');
xlabel('x');
ylabel('y');
```
Hope this helps!
