A= {[0.2 0.5 0.3] [ 0.1 0.1 0.3]}
A=cell2table(A)
B=[ 2 3]
A*B must be {[0.4 1 0.6] [0.3 0.3 0.9]}

I prefer Adam's method :
although if you want to multiply table with matrix then=>
arrayfun(@(x) A{:,x}*B(x),1:numel(B),'un',0)

Why all the complications with cell arrays and tables? Just use numeric arrays:
A = [0.2 0.5 0.3; 0.1 0.1 0.3];
B = [2;3];
C = A.* B;
or
C = bsxfun( @times, A, B );
if you have an older version of Matlab.
