I need to sample a continuous time sine wave via MATLAB. For example, I need 19 samples of a sine wave. But the output, i.e. the sample data I need in a text file, so that I can use it in my FPGA software. How shall I do it?

Something along these lines?
t = linspace(0,2*pi,1000) ;
y = 100 * sin(2*pi*1.8*t) ;
s = sort(randperm(numel(t),19)) ; % 19 random points, sorted
plot(t,y,'b.-', t(s), y(s),'ro') ; % check
data = [t(s) ; y(s)].'
dlmwrite('export.txt',data)

In addition to the Answer above, please see the following page for how to generate HDL code from MATLAB code and deploy to an FPGA: https://www.mathworks.com/help/hdlcoder/targeting-fpga-amp-soc-hardware.html
