How might I address this error?

Error using double Conversion to double from cell is not possible.

The associated line of code is simply: (mat1)=double(mat2);

It means that mat2 is a cell array and you cannot immediately cast it to a double. Depending on the contents of mat2, perhaps you can use cell2mat

     x = cell(2,1);
     x{1} = randn(10,1,'single');
     x{2} = randn(10,1,'single');
     % double(x) this throws the error you report
     y = double(cell2mat(x)); % this does not

But you should show us a simple model of what your cell array looks like.

Please take the time to read the error message again:

Conversion to double from cell is not possible.

This means, it is hard to express it in other words, that your code tries to convert a cell to a double, and this is not possible. Matlab's error messages are the best I've ever seen.

But as Wayne has explained already, you can convert the elements of a cell to a double array.
