hi,
I have a character array, for example:
vars = ['X';'Y']
I want to assign the name of an element in vars to a double array, such as:
for i=1:2
char(vars(i,:)) = rand(10,1)
end
Unfortunately this does not work as I am obviously attempting to equate a character array to a double array of different length. Instead of course what I was attempting to do is name a double array from a predefined list.
Please help!
thx

Do not do this. Creating variables dynamically a is common and frequent source of errors. In addition is is slow. See:
Use either an array, cell array or struct:
vars = {'X', 'Y'};
S = [];
for i = 1:2
S.(vars{i}) = rand(10,1);
end
Or:
C = {};
for i = 1:2
C{i} = rand(10,1);
end
