hi..I had a problem relating to the calculation of the boolinger band Using the matlab function (bollinger) is the result equal to the calculation of the standard deviation of its n-period mean? Unfortunately I can't do this test because I need the stdev2 function which is a paid package

Which software package is stdev2 part of? It does not appear to be a Mathworks function

The std2 function takes the standard deviation of all the elements in an array (it only has one argument, that being the entire array). You might be able to create your own version of it with:
std2 = @(A) std(A,[],'all');
This has been possible since R2018b.
EDIT —
Since the bollinger function has to have access to std2, use:
function sda = std2(A)
sda = std(A,[],'all');
end
instead, and store it as std2.m on your MATLAB search path where bollinger can find it.

function sda = std2(A)
sda = std(A,[],'all');
end
as std2.m on your MATLAB search path so that all calls to it can find it.
