sir ,
i have created a signal.
%%%%%%%%%%%%%%%%%%%%
clc;
clear all;
ff=100000:50000:400000;
x = length(ff);
Ytot=0.0;
for j=1:1
R=4E+6; % Synchronized Rate (Max)
dt=1/R; % Sampling Time for output
f=ff(j);
t=0;
y=0;
Y=0;
Y1=0;
N=5; % Number of cycles
L=N/(dt*f); % Length of signal
for i=1:L
Y1(i)=4*(1-cos(t*2*pi*f/N))* sin(t*2*pi*f);
t=t+dt;
end
for i=1:L
Y(i)=0.0;
end
Y=[Y Y1 ];
if j==1
Ytot=[Y];
else
Ytot=[Ytot Y];
end
end
t=([1:1:length(Ytot)])*dt;
subplot(2,1,1)
plot(t,Ytot);
%%%%%%%%%%%%
i want to insert certain constant values say for t=(.6-.8)^10-4
i want to insert values based on knowlege of only x-axis values
i dont want to use anycode that uses index.
my code should depend entirely on x values
