how to generate a sine function of time with 1024 second long ... and generate 8 full cycle over this interval ....

How many samples do you want over that 1024 seconds? Let's say it's 50,000:

numSamples = 50000;
t = linspace(0, 1024, numSamples);
period = numSamples / 8; % Want 8 full cycles
amplitude = 1; % Whatever.
y = amplitude * sin(2 * pi * t / period);
plot(t, y, 'b-', 'LineWidth', 2);
grid on;
xlabel('t', 'FontSize', 20);
ylabel('y', 'FontSize', 20);

I need 1024 sample only ... I just try to run tghis code but it gives error

numSamples = 1024;
t = linspace(0, 1024, numSamples);
period = numSamples / 8; % Want 8 full cycles
amplitude = 1; % Whatever.
y = amplitude * sin(2 * pi * t / period);
plot(t, y, 'b-', 'LineWidth', 2);
grid on;
xlabel('t', 'FontSize', 20);
ylabel('y', 'FontSize', 20);
