p= (B-(b*t))/(sigma);
I need this equation to be plot as t increase by 1
for t= 0:1:
p(t)= (B-(b*t))/(sigma); plot(t,p)
How do I do it? Please help

t = 0 : 0.1 : 1;
for K = 1 : length(t)
p(K) = (B-(b*t(K)))/(sigma);
end
plot(t, p)
(Note: there are more efficient ways of doing it, but this is the closest correspondence to your current code.)

Could you fix this code?
tt=1000; B=1700; b=0.0013; sigma=0.0099;
t = 0 : 1 : tt; for K = 1 : length(t) p(K) = (B-(b*t(K)))/(sigma); end p(K)= roundn(p,-1); p(K)=p;
if p==0.0 l=.5*k; elseif p==0.1 l=.5478*k; elseif p==0.2 l=.5793*k; elseif p==0.3 l=.6255*k; elseif p==0.4 l=.6554*k; elseif p==0.5 l=.6985*k; elseif p==0.6 l=.7257*k; elseif p==0.7 l=.7642*k; elseif p==0.8 l=.7881*k; elseif p==0.9 l=.8212*k; elseif p==1.0 l=.8413*k; elseif p==1.1 l=.8686*k; elseif p==1.2 l=.8849*k; elseif p==1.3 l=.9066*k; elseif p==1.4 l=.9192*k; elseif p==1.5 l=.9357*k; elseif p==1.6 l=.9452*k; elseif p==1.7 l=.9573*k; elseif p==1.8 l=.9641*k; elseif p==1.9 l=.9726*k; elseif p==2.0 l=.9772*k; elseif p==2.1 l=.9830*k; elseif p==2.2 l=.9861*k; elseif p==2.3 l=.9898*k; elseif p==2.4 l=.9918*k; elseif p==2.5 l=.9941*k; elseif p==2.6 l=.9953*k; elseif p==2.7 l=.9967*k; elseif p==2.8 l=.9974*k; elseif p==2.9 l=.9982*k; elseif p==3.0 l=.9987*k; elseif p>3.0 l=1*k; elseif p==-0.1 l=.4522*k; elseif p==-0.2 l=.4207*k; elseif p==-0.3 l=.3745*k; elseif p==-0.4 l=.3446*k; elseif p==-0.5 l=.3015*k; elseif p==-0.6 l=.2743*k; elseif p==-0.7 l=.2358*k; elseif p==-0.8 l=.2119*k; elseif p==-0.9 l=.1788*k; elseif p==-1.0 l=.1587*k; elseif p==-1.1 l=.1314*k; elseif p==-1.2 l=.1151*k; elseif p==-1.3 l=.0934*k; elseif p==-1.4 l=.0808*k; elseif p==-1.5 l=.0643*k; elseif p==-1.6 l=.0548*k; elseif p==-1.7 l=.0427*k; elseif p==-1.8 l=.0359*k; elseif p==-1.9 l=.0274*k; elseif p==-2.0 l=.0228*k; elseif p==-2.1 l=.0170*k; elseif p==-2.2 l=.0139*k; elseif p==-2.3 l=.0102*k; elseif p==-2.4 l=.0082*k; elseif p==-2.5 l=.0059*k; elseif p==-2.6 l=.0047*k; elseif p==-2.7 l=.0033*k; elseif p==-2.8 l=.0026*k; elseif p==-2.9 l=.0018*k; elseif p==-3.0 l=.0013*k;
else l=0*k; end
plot(t, p)

X = sin(3 t) cos(t), y = sin(3 t) sin(t)
