what is the meaning of code?

t = 5;
nt = length(invest(:,1));
n = nt/t;

qn = 400;            % number of quantiles to examine

what does this nt, n= nt/t mean and how no of quantiles are determined in data to enter i code.

[Walter Roberson]

nt/t means nt is to be divided by t -- so the number of rows is to be divided by 5.

Why that should be done is not known from the context you have given.

what does q=400 mean and why we take 400 quantiles

[Image Analyst]

You have shown no code after qn has been defined so we have no idea how it's going to be used.

[Walter Roberson]

q=400 means to assign the double precision representation of the integral value (decimal) 400 to the variable named "gn".

Why that should be done is not known from the context you have provided.
