Given is a matrix A of size [1x6]. What I want is to copy the elements of A to a set of variable names [a,b,c,d,e,f], so that

a = A(1);
b= A(2)
a.s.o.

I tried

[a,b,c,d,e,f] = deal(A);

But this copies not the elements but the hole matrix A into each variable.

Any help is much appreciated.

Acell = num2cell(A);
[a,b,c,d,e,f]  = deal(Acell{:});    %older MATLAB
[a,b,c,d,e,f]  = Acell{:};          %newer MATLAB

Thanks Walter. This is quite simple. And I do not have any problems with definition of what workspace it is.

Thank you, Azzi for your help too.

% generates function handle to bimodal gaussian distribution:
% f(X; A1, A2, x01, x02, sig1, sig2) = ...
%  A1*exp( -(X-x01).^2 / (2*sig1^2) )  +  A2*exp( -(X-x02).^2 / (2*sig2^2) )
% beta is the coefficient vector [A1,A2,x01,x02,sig1,sig2]
function f = bimodgauss(beta)
s={'A1','A2','x01','x02','sig1','sig2'};
for k=1:numel(s)
assignin('caller',s{k},beta(k))
end
f = @(X) A1*exp(-(X-x01).^2 / (2*sig1^2))  +  A2*exp(-(X-x02).^2 / (2*sig2^2));
