MATLAB: Adding arrays found using ‘who’ function

Question

Hello,

I have used the 'who' function to obtain the required 2D numeric arrays from a list of variables, like this;

Find_Target_Vars = who ('Target_Str')

Find_Target_Vars =

    'A'
    'B'
    'C'

I now need to create a new (numeric,double) variable D, so that D = A + B + C.

How can I get from the list of variables in the cell array, Find_Target_Vars, to adding the actual listed variables together?

Many thanks, Iain

This is one of the (rare) cases EVAL comes in handy.

evalStr = sprintf('%s+', Find_Target_Vars{:}) ;
evalStr = evalStr(1:end-1) ; % remove trailing +
D = eval(evalStr)
