Collect coefficients of array variables during calculation:

Hello Mathematica Friends If we have an array variable, and assuming after intermediate calculations, some equations are found to be below. eqn1=10. A[[1,1]]+b A[[1,1]]+c A[[1,2]]+3. A[[1,2]] (only for illustration) Simplify[] does not combine the coefficients under same array member, i.e. instead of (10.+b)A[[1,1]]+(c+3.)A[[1,2]], it is showing the earlier mentioned form. Is there a way to collect them and simplify them. But when I checked for simple cases, Simplify[] seems to work. Thanks for the suggestions. Regards, Gopinath University of Oklahoma
