how to write equation given below to find corresponding plot?

equation is given here

 s(x)=(2a/T)*(x)   when 0<=x<=T/2;
     =2a*(1-x/T) when T/2<=x<=T;

here a=0.1 and T=20

Try this:

a = 0.1;
T = 20;

s = @(x) (2*a*x/T) .* (0<=x & x<=T/2) + (2*a*(1-x/T)) .* (T/2<=x & x<=T);

x = linspace(0, 20);
sv = s(x);

figure(1)
plot(x,sv)
hold on
for k1 = 20:20:60
    plot((x+k1),sv)
end
hold off

My pleasure.

‘i want to create this plot in two dimension image’

It is a two dimension plot. I have no idea what other result you want. Do you have an example?

sir i want to convert that triangular waveform into triangular fringe pattern, i have an example given below %sinusoidal wave form t=0:1/100:1; f=5; I=sin(2*pi*f*t); plot(I); % sinusoidal fringe pattern m=1000; % rows n=1000; % column f1=20; % No. of vertical fringes f2=0; % No. of horizontal fringes for i=1:m for j=1:n a(i,j)=sin(2*pi*(f1*j/n+f2*i/m)); end end imshow(a,[])

I believe I already addressed this in your other Question.
