How to write the below code in matlab as itis asking the value of x?

NSD(x)=NSD(p)*exp(-x^2/2*lateralstraggle^2)

Error shown is : Undefined function or variable 'p'.

What do you think p should be? And what is x? MATLAB is not going to know unless you tell it. What if MATLAB just arbitrarily assumed 42 for p when you were thinking it should be 73 but you didn't tell MATLAB that? Would you like it to pick some value for p that you don't like?

so we need to declare the value of p. but the value of Nsd(p)=1*10^20 again it is showing error

This works perfectly fine. I know because I just tried it:

p=42; % Declare p to be some value.
Nsd(p)=1*10^20

You forgot to post your error. And you forgot to tell me what value x has.
