Symbolic computation

Could you tell me how to define a array containing more than hundred symbolic variable using loop or commands?

Answer 1

[Andrei Bobrov]

e.g. (R2011b):

A = sym('A',[10 10])
A1 = sym('A1_',[100 1])

OR

[x y] = meshgrid(1:10);
for i1 = 1:numel(x)
    A2(y(i1),x(i1)) = sym(sprintf('A2_%d_%d',y(i1),x(i1)));
end

OR

[x y] = meshgrid(1:10);
k = arrayfun(@(i1)sym(sprintf('A3_%d_%d',y(i1),x(i1))),1:numel(x),'un',0);
A3 = reshape([k{:}],10,[]);

Note: that form of sym() is relatively new. R2010b or so.

thank you for your answer. Now I'm using matlab 2008.
