I have two scripts. In first script I have some functions.
script1.m:
function res = func1(a)
res = a * 5;
end
function res = func2(x)
res = x .^ 2;
end
In second script I call these functions. How to include script1.m in second script and call functions from script1.m?

You can't if the functions are defined as local functions in the script1 file.
Just put the functions in their own separate file (of the same name as the function and on your path) if they are being used by both script1 and script2.

Thanks! I'll try. The script can be saved as script.m as well and call the numtimes2.m?

Yes. A script can call its own local functions, or it can call a function file like numtimes2().

You can add them to a MATLAB class. Then instantiate an object of this class and call any of the functions.
It should be something like this:
In a separate file (ex, functionsContainer.m)
classdef functionsContainer
methods
function res = func1(obj,a)
res = a * 5;
end
function res = func2(obj,x)
res = x .^ 2;
end
end
end
Then, in your script create an object:
myObj = functionsContainer;
Finally, call whatever function you like:
res1 = myObj.func1(a);
res2 = myObj.func2(x);

if you define the methods as static, you dont even have to instantiate the class
E.g:
classdef Functions
methods(Static)
function y = func1(x)
% body
end
function y = func2(x)
% body
end
end
end
And then you can run from another script or cmd:
output = Functions.func1(input)
