Is there any way in MATLAB to access a variable whose name is expressed by another string variable?
for example, when
myvar = 10;
string_myvar = "myvar";
were in the workspace and substituting the numerical scalar myvar into another myvar2 as
myvar2 = myvar;
Id’ like to find a way to give the right hand side "as the content of string scalar ‘string_myvar’ ".

Get rid of FIND: logical indexing is simpler.
The robust and efficient approach would be to put all of the variables into one container array (e.g. structure, cell array, table) and then use ISMEMBER or dynamic fieldnames or something similar to select the ones for the output.
For example:
C = {arg1,arg2,..,argN};
N = {'x1','x2',..,'xN'};
userwants = ["x1","x3"];
[X,Y] = ismember(userwants,N);
assert(all(X),'no match')
varargout = C(Y)
