Hello,
I have a big structure. First column is numbers, but other columns (each cell of the column) are each a vector. Those vectors show as single, I want to convert them all to double. There are almost 300 of those vector-cells.
Can you help there?

new_cell_array = cellfun(@double, existing_cell_array, 'uniform', 0);

I do not understand what you mean by "column" with respect to a struct ? You have a structure array, and a column of a structure array would be like YourStructure(:, 3) for column three, giving a scalar struct (since you only have one row), but a struct itself cannot be numeric type.
Are you talking about fields? That fields number 2, 3, 4, 5, 6, 7 show up as single ?
Would it be acceptable to convert all of the fields to double, or are there some non-numeric fields?

to fix Error using cellfun Input #2 expected to be a cell array, was struct instead, try:
new_cell_array = structfun(@double, existing_cell_array, 'uniform', 0);
