Hi
I wanna make a vector with variable names and then assign values to the from a for loop.
Estimates = [1 2 3 4 5 6 7];
variables = (a b c d e f g};
for i = 1:length(variables)
variables(i) = Estimates(1);
end
So that
a = 1 b = 2 etc
and so on. Is this possible?
And also is i possible to make it so that you create variables named in incremental way? I.e
b = [2 5 45];
for i = 1:length(b)
'a'+int2str(i) = b(i);
end
that is
a1 = 2 a2 = 5 and a3 = 45
Kind Regards

yes this is possible. you could use the command "eval" that comes with matlab. have a look at the documentation.
for your case you would have to change the variables array to have chars inside - i.e.:
vars = {'a', 'b', 'c'}
and in the for loop use
vals = [1 2 3 4]
vars = {'a', 'b', 'c', 'd'}
for i = vals
eval([vars{i} '= vals(i)'])
end
also, you might want to have a look at the "genvarname" command of matlab that does exactly what you want in the second part of your question.

While you can do this with eval, it is generally not recommended. This is pretty well covered in the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F
