How can I generate a sinusoidal wave in Matlab in one plot?

Duration 0-1, Step 0.02

Frequency 20 Hertz

Plot it across time duration (t)

t_start = 0;
t_end = 1;
t_step = 0.002; % 0.002 looks more like a sinusoid than 0.02, but do what you like

f = 20;
t = linspace(t_start,t_end,round((t_end-t_start)/t_step)+1);
x = sin(2*pi*f*t);

plot(t,x);
